BLE sensors data through a connect, LYWSD03MMC and MHO-C401 add (#736)

Browse Source 
* Add LYWSD03MMC and MHO-C401 device
and an associated BLE connect mechanism as these devices advertise only encrypted data
-free manufacturer data
-update library

* Implement scans number before connect
-Add the possibility to do a connect every X scan
-Rename variables for consistency
-Some refactoring for improved code reading

Once done the previous value of interval will be recovered.
Once the forced scan has completed, the previous scan interval value will be restored. Forcing a scan command trigger also a BLE connect process after the scan (see below).
The default value is set into config_BT.h
The default value `TimeBtwRead` is set into config_BT.h or into your .ini file for platformio users.

For certain devices like LYWSD03MMC OpenMQTTGateway use a connection (due to the fact that the advertized data are encrypted), this connection mechanism is launched after every `ScanBeforeConnect` per default, you can modify it by following the procedure below.

## Setting the number of scans between before connect attempt
If you want to change the number of BLE scans that are done before a BLE connect you can change it by MQTT, if you want the BLE connect to be every 30 scans:

The BLE connect will be done every 30 * (`TimeBtwRead` + `Scan_duration`), 30 * (55000 + 10000) = 1950000ms :
