Pybit

Modified

- `requests` will use `JSONDecodeError` from `simplejson` if it is available—`pybit` will now do the same to prevent
errors.
- Fixed a bug where `HTTP` retry would crash on rate limit reached due to undefined variable.
- Improved `InvalidRequestError` and `FailedRequestError` to include error codes and times.

Modified

- `WebSocket` will now temporarily differentiate between inverse and linear endpoints for the 'order' topic
since incoming data has differing keys.

Added

- `WebSocket` now has `purge_on_fetch` (defaults to `True`), which allows the user to keep data between fetches.

Modified

- Fixed a bug on 'stop_order' for `WebSocket` that would prevent data from being appended due to deprecation
of `stop_order_id`.

- See release candidates for details.

Modified

- Rewrote if-condition on `_on_message` in `WebSocket` class to check for linear or non-linear position data.

Modified

- Added ability to handle `from` using `from_time` and `from_id` arguments since `from` is a
reserved keyword.
- Removed `ignore_retries_for` from `HTTP`. `pybit` now uses a standard list of non-critical errors that can
be retried.
- Added argument `retry_delay` for `HTTP`—allows user to add a custom retry delay for each retry.
