Datacube

- Added origin, alignment and `GeoBox`-based methods to `model.GridSpec`
- Fixed satellite path/row references in the prepare scripts (Thanks to Chris Holden!)
- Added links to external datasets in Indexing Data
- Improved archive and restore command line features: datacube dataset archive and datacube dataset restore
- Improved application support features
- Improved system configuration documentation

- `GridWorkflow.list_tiles` and `GridWorkflow.list_cells` now
return a `Tile` object
- Added `resampling` parameter to `Datacube.load` and `GridWorkflow.load`. Will only be used if the requested data requires resampling.
- Improved `Datacube.load` `like` parameter behaviour. This allows passing in a `xarray.Dataset` to retrieve data for the same region.
- Fixed an issue with passing tuples to functions in Analytics Expression Language
- Added a `Recipes` section to the documentation containing useful code snippets
- Reorganized project dependencies into required packages and optional 'extras'
- Added `performance` dependency extras for improving run-time performance
- Added `analytics` dependency extras for analytics features
- Added `interactive` dependency extras for interactivity features

- Added bit shift and power operators to Analytics Expression Language
- Added `datacube product update` which can be used to update product definitions
- Fixed an issue where dataset geo-registration would be ignored in some cases
- Fixed an issue where Execution Engine was using dask arrays by default
- Fixed an issue where int8 data could not sometimes be retrieved
- Improved search and data retrieval performance

- Improved spatio-temporal search performance. `datacube system init` must be run to benefit
- Added `info`, `archive` and `restore` commands to `datacube dataset`
- Added `product-counts` command to `datacube-search` tool
- Made Index object thread-safe
- Multiple masking API improvements
- Improved database Index API documentation
- Improved system configuration documentation

- Updated the way database indexes are patitioned. Run `datacube -v system init` to update indexes
- Added `fuse_data` ingester configuration parameter to control overlaping data fusion
- Added `--log-file` option to `datacube dataset add` command for saving logs to a file
- Added index.datasets.count method returning number of datasets matching the query

- Improved dataset search performance
- Restored ability to index telemetry data
- Fixed an issue with data access API returning uninitialized memory in some cases
- Fixed an issue where dataset center_time would be calculated incorrectly
- General improvements to documentation and usablity
