SubGhz: Add Chamberlain 7-Code, Chamberlain 8-Code, Chamberlain 9-Code (#1288)

* SubGhz: fix protocol MegaCode start duration
* SubGhz:  add reception Chamberlain Code 7, 8, 9 protocols
* SubGhz: Generating an upload from HEX data and a duration of 1 bit
* SubGhz: add transmit Chamberlain Code 7, 8, 9 protocol
* SubGhz: Rename Firefly -> Linear
