Some Python types weren't being reported or were inconsistent. Fixed the ones I noticed.

- Add Breaker PIN support for EVSE. If a Breaker PIN is set it will be passed on update requests.
- v0.17.0 added endpoints for updating some settings on channels, such as name, and getting the channel types.
- v0.17.0 also forced usernames to be lowercase no matter what casing they're provided.

- Added `get_devices_status` function to replace `get_outlets` and `get_chargers`. Returns both sets in one API call and can update the `connected` state of devices. The older methods still exist but will be removed in the future.
- Merged PR 36 to set a default timeout on requests. Defaults at 6 seconds for connects and 10 seconds for reads.
- Added typing hints for all functions and a number of variables.
- Updated a few of the test scripts. `outlet_test.py` will also print out EV chargers. Running the module directly should properly print out the access token and will now print out the state of any outlets or EV chargers. Both files now take advantage of the typing hints as well.

This release refactors the authentication to be more in line with what Home Assistant expects for managing tokens and replaces the use of warrant with pycognito. The automatic storing of tokens has also changed to use "username" and underscores for things like "id_token". This also fixes the parsing issue in 30.
