* Expose current and latest firmware as features
* Provide API to get information about available firmware updates (e.g., changelog, release date etc.)
* Implement updating the firmware
Moves `FeatureType` into `Feature` to make it easier to use the API.
This also enforces that no invalid types are accepted (i.e.,
`Category.Config` cannot be a `Sensor`)
If `--verbose` is used with the cli tool, some extra information is
displayed for features when in the state command.
Devices not connected to the internet will either error when querying
firmware queries (e.g. P300) or return misleading information (e.g.
P100). This PR adds the cloud connect query to the initial queries and
bypasses the firmware module if not connected.
Also updates CI pypy versions to be 3.9 and 3.10 which are the currently
[supported
versions](https://www.pypy.org/posts/2024/01/pypy-v7315-release.html).
Otherwise latest cryptography doesn't ship with pypy3.8 wheels and is
unable to build on windows.
Also updates the `codecov-action` to v4 which fixed some intermittent
uploading errors.
