This release updates the snap to [Theengs Gateway v0.9.0](https://github.com/theengs/gateway/releases/tag/v0.9.0), including [Theengs Decoder v1.3.7](https://github.com/theengs/decoder/releases/tag/v1.3.7). This adds presence detection, LWT message handling and some new decoders.

This release updates the snap to [Theengs Gateway v0.8.0](https://github.com/theengs/gateway/releases/tag/v0.8.0), including [Theengs Decoder v1.1.0](https://github.com/theengs/decoder/releases/tag/v1.1.0). This fixes some decoders, supports two new devices, and adds time synchronization support for more devices than the LYWSD02.

Note that time synchronization isn't enabled anymore by default. You need to specify the addresses of the BLE devices you want to synchronize, e.g. with `snap set theengs-gateway time-sync.addresses="12:34:56:78:9A:BC FE:DC:BA:98:76:54"`.
