Merge branch 'dev-0.12' of https://github.com/s-allius/tsun-gen3-proxy into titan-scan

S allius/issue205 (#207 )
* Add SolarmanEmu class * Forward a device ind to establish the EMU connection * Move SolarmanEmu class into a dedicated file * Add cloud connection counter * Send inverter data in emulator mode * Improve emulator mode - parse more values from MQTT register - differ between inverter and logger serial no * Add some unit tests for SolarmanEmu class * Send seconds since last sync in data packets * Increase test coverage
