[FL-2920] WS: add protocol Acurite-606TX, LaCrosse_TX141THBv2 (#1898)

* WS: add protocol Acurite-606TX
* WS: history, added display of the channel (if any) in the general list
* WS: added display of the button state if it is on the transmitter, and displaying the data that is in the signal
* WS: fix batt info
* WS: add protocol LaCrosse_TX141THBv2
* WS; fix syntax
* Furi: bump api_symbols version
