Esp32 compatibility (#145)

* esp32 init

* RF gateway ok with ESP32

* correct IR gateway compilation errors and test RF2 ok

* divide config per board type

* update test file according user_config

* differentiate variable type following IR libraries aka platforms

* implement BLE beacons detection with ESP32

* Implement multitasking on BLE gateway

* Library add and change core assignement

* change core assignement for BLE

* add mi flora value readings with ESP32

* adding some traces and removing unecessary comment

* correct compilation error due to pin assignement

* correct temperature float value and wrong mac adress rssi publishing

* add esp32 to CI

* correct esp32 ide retrieving

* correcting paths

* CI: correct architecture
* libraries update (irremote) and overwrite ble library files
