[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 Co-authored-by: あく <alleteam@gmail.com>
