* Initial orjson support take 2
Still need to work out problem building wheels
--
Redux of #72754 / #32153 Now possible since the following is solved:
ijl/orjson#220 (comment)
This implements orjson where we use our default encoder. This does not implement orjson where `ExtendedJSONEncoder` is used as these areas tend to be called far less frequently. If its desired, this could be done in a followup, but it seemed like a case of diminishing returns (except maybe for large diagnostics files, or traces, but those are not expected to be downloaded frequently).
Areas where this makes a perceptible difference:
- Anything that subscribes to entities (Initial subscribe_entities payload)
- Initial download of registries on first connection / restore
- History queries
- Saving states to the database
- Large logbook queries
- Anything that subscribes to events (appdaemon)
Cavets:
orjson supports serializing dataclasses natively (and much faster) which
eliminates the need to implement `as_dict` in many places
when the data is already in a dataclass. This works
well as long as all the data in the dataclass can also
be serialized. I audited all places where we have an `as_dict`
for a dataclass and found only backups needs to be adjusted (support for `Path` needed to be added for backups). I was a little bit worried about `SensorExtraStoredData` with `Decimal` but it all seems to work out from since it converts it before it gets to the json encoding cc @dgomes
If it turns out to be a problem we can disable this
with option |= [orjson.OPT_PASSTHROUGH_DATACLASS](https://github.com/ijl/orjson#opt_passthrough_dataclass) and it
will fallback to `as_dict`
Its quite impressive for history queries
