refactor: BLE scanning instead of connecting to BLE devices (#243)

* refactor: passive scan instead of connecting to BLE devices

* refactor: increased disconnected timeout for sensors

* fix: build for nodemcu32, c3, c6 boards; formatting ``platformio.ini``

* refactor: decreased interval and window for scanning BLE

* refactor: active + passive BLE scanning

* refactor: reduced tasks stack size

* style: formatting

* refactor: improved OTA upgrade

* chore: fix dependencies

* chore: reformat `platformio.ini`

* chore: dependencies fixed

* feat: added support BTHome v2 format for BLE sensors #215

* refactor: cosmetic changes

* fix: move OpenThermTask to 0 core

* chore: minimizing flash size with NimBLE

* chore: dependencies updated
