Pyinaturalist

* Add undocumented `ident_user_id` parameter to `get_observations()`

[See all Issues & PRs for 0.12](https://github.com/pyinat/pyinaturalist/milestone/3?closed=1)

New Endpoints
* Added new function for **Observation Histogram** endpoint: `get_observation_histogram()`
* Added new function for **Observers** endpoint: `get_observation_observers()`
* Added new function for **Identifiers** endpoint: `get_observation_identifiers()`
* Added new function for **Controlled Terms** endpoints: `get_controlled_terms()`
* Wraps both `GET /controlled_terms` and `/controlled_terms/for_taxon` endpoints

Modified Endpoints
* Added conversion from date/time strings to timezone-aware python `datetime` objects.
This applies to the following functions:
* `node_api.get_observation()`
* `node_api.get_observations()`
* `node_api.get_all_observation()`
* `node_api.get_projects()`
* `node_api.get_projects_by_id()`
* `node_api.get_taxa()`
* `node_api.get_taxa_by_id()`
* `rest_api.get_observation()`
* `rest_api.get_observation_fields()`
* `rest_api.get_all_observation_fields()`
* Added conversion for an additional `location` field in observation responses

Authentication
* Added support for providing credentials via environment variables
* Added integration with system keyring for credentials storage
* Added documentation & examples for authentication options

Other Changes
* Added a `Dockerfile` and `docker-compose.yml` for a Jupyter notebook containing pyinaturalist + other relevant packages
* Added some more detailed usage examples under `examples/`
* Improved performance for large paginated queries
* Fixed bug that dropped request parameter values of `0` as if they were `None`
* Dropped support for python 3.5
* Removed request parameters that were deprecated in 0.11

New Endpoints
* Added new functions for Node API **Places** endpoints:
* `get_places_by_id()`
* `get_places_nearby()`
* `get_places_autocomplete()`
* Added new functions for Node API **Projects** endpoints:
* `get_projects()`
* `get_projects_by_id()`
* Added new function for an additional Node API **Observation** endpoint:
* `get_observation_species_counts()`
* `get_all_observation_species_counts()`

Modified Endpoints
* Added support for simplified observation field syntax (`observation_fields={id: value}`)
for `create_observations()` and `update_observation()`
* Updated `node_api.get_taxa_by_id()` to accept multiple IDs
* Updated `rest_api.get_observations()` with type conversion from strings to floats for response lat/long coordinates.
Only applies to JSON response format.
* Updated `node_api.get_taxa_autocomplete()` with optional `min_rank` and `max_rank` parameters, for consistency with `get_taxa()`
* Using the `params` positional argument for the handful of functions that used it
will raise a `DeprecationWarning`, but will otherwise still be functional until `0.12`
* Renamed `search_query` argument to `q` to be consistent with API request parameters
* Using the `search_query` argument for `rest_api.get_observation_fields()` and `rest_api.get_all_observation_fields()`
will raise a `DeprecationWarning`, but will otherwise still be functional until `0.12`
* Renamed `create_observations()` to `create_observation()`, as this only supports creating a single observation per
call. This is aliased to `create_observations()` for backwards-compatibility, but will raise a `DeprecationWarning`.

Documentation & Usability
* Added example response data to docs all endpoints
* Added links to official API reference to docs for all endpoints
* Added full API request parameters to all API functions, in the form of keyword arguments with type annotations and docstrings
* Added complete table of iNaturalist API endpoints and endpoints implemented by pyinaturalist
* Added and improved usage examples
* Numerous other documentation improvements
* Made all API function signatures consistent by taking request params as keyword arguments

Other Changes
* Dropped support for python 3.4
* Added support for python 3.9
* Added parameter validation for multiple-choice request parameters

[See all Issues & PRs for 0.10](https://github.com/pyinat/pyinaturalist/milestone/1?closed=1)

New Endpoints
* Added new **Observation** endpoint: `rest_api.get_observations()`, with 6 additional observation response formats, including GeoJSON, Darwin Core, and others

Modified Endpoints
* Added `minify` option to `node_api.get_taxa_autocomplete()`

Other Changes
* Added more info & examples to README for taxa endpoints, and other documentation improvements
* Added conversion for all date and datetime parameters to timezone-aware ISO 8601 timestamps
* Added a dry-run mode to mock out API requests for testing
* Set up pre-release builds for latest development version

-----

* Bugfix: proper support for boolean and integer list parameters ([Issue 17](https://github.com/pyinat/pyinaturalist/issues/17))

New Endpoints
* Added new functions for Node API **Taxa** endpoints:

* `node_api.get_taxa()`
* `node_api.get_taxa_autocomplete()`
* `node_api.get_taxa_by_id()`
