Reduce payload sizes by adding support for short UUIDs and compact json

[bdraco]

/accessories payloads sizes are now reduced by ~40%+ with:

• Apple defined uuids should be reduced to their short form to reduce the payloads

• description (optional) is only included in the payload if it has been customized

• compact json

• fixes events not being utf-8 encoded

This solved another case of iOS getting stuck updating when the bridge has many devices

This does quite a bit to reduce payload sizes and improve performance since the encrypted payloads are much smaller.

@ikalchev Can we get a release with this for this week's Home Assistant beta?

Thanks!
