2.0.0

This new major version of parfive tackles the usability of the API.

The API of parfive grew organically as support for more use cases were added.
To enable both a highly flexible downloader that can be used for any HTTP/FTP downloads while maintaining an accessible and simple API with the 2.0 release there is now a `parfive.SessionConfig` object where advanced settings are located.

The other major change in this release is that any files where the download failed before it is completed will be removed from disk. This means that you shouldn't end up with incomplete and corrupt files on disk if the download is interrupted for any reason.

Breaking Changes

* The `file_progress`, `notebook`, `use_aiofiles`, and `header` keyword arguments to `parfive.Downloader` have been removed and moved into the `parfive.SessionConfig` object.
* The `timeouts` keyword argument has been removed from the `run_download()` and `download()` methods and replaced by an option in `SessionConfig`.

Enhancements
* Improve repr of Results, remove files from disk if download errors before completing and add max_splits as a keyword argument to Downloader by nabobalis in https://github.com/Cadair/parfive/pull/76
* Add a new `SessionConfig` object to allow advanced configuration of the `Downloader` by Cadair in https://github.com/Cadair/parfive/pull/92
* A new `PARFIVE_HIDE_PROGRESS` environment variable will disable all progress bars.
* All environment variables are now evaluated at the time the `Downloader` class is instantiated (by the new config classes).
* It is now possible to customise the instantiation of the `aiohttp.ClientSession` by passing a function to the `aiohttp_session_generator=` keyword argument to `SessionConfig`.
* It is now possible to configure debug or other levels of logging with `SessionConifg` where previously it could only be configured with an environment variable.
* It is now possible to configure the HTTP chunksize with `SessionConfig` and the default when not using aiofiles has been increased from 100 bytes to 1024 bytes.
* It is now possible to configure the HTTP(S) proxy URLs with `SessionConfig` as well as the `HTTP[S]_PROXY` environment variables.
* It is now possible to customise all the timeouts supported by aiohttp by passing an `aiohttp.ClientTimeout` object to `SessionConfig`.
* Improve the CLI with more options by Cadair in https://github.com/Cadair/parfive/pull/103
* Cleanup after Keyboard interrupt correctly by Cadair in https://github.com/Cadair/parfive/pull/104
* This means that the download will be killed correctly when the download is interrupted.
* Note that is does not work on Windows due to the lack of support for signal handling in `asyncio` on Windows.
* Remove deprecated loop keyword argument by Cadair in https://github.com/Cadair/parfive/pull/88
* Use tqdm's auto notebook detection by Cadair in https://github.com/Cadair/parfive/pull/90

* Fix a bug where only HTTP 200 response codes were accepted as success by SolarDrew in https://github.com/Cadair/parfive/pull/95
