[FL-1610] SubGhz: scene based application, PT save and replay (#630)
* SubGhz: scene based application
* SubGhz: encoder/decoder separation, DMA streaming, update app and cli.
* SubGhz: 2 stage async tx complete, minor cleanup
* SubGhz: 2 stage async tx complete, FIX state pin end transmit
* SubGhz: Pricenton, receive TE signal
* SubGhz: Pricenton, add save data, add load data
* SubGhz: Add Read scene, Fix pricenton save, load funtion
* SubGhz: Add Read, Receiver, SaveName scene
* SubGhz: Read and Save (pricenton)
* SubGhz: add Load scence
* SubGhz: Fix select file scene, add load scene, add transmitter view, add send tx pricenton
* SubGhz: Fix pricenton encoder, fix transmitter send
* SubGhz: modified Pricenton Encoder (added guard time at the beginning), modified CC1101 config, code refactoring
* SubGhz: Fix pricenton encoder defalut TE
* Archive: Fix path and name SubGhz
* Archive: Fix name app SubGhz
* GubGhz: Came: add Save, Load key
* GubGhz: GateTX: add Save, Load key
* GubGhz: NeroSketch: add Save, Load key
* Github: better linters triggers
* SubGhz: adding fast loading keys Archive -> Run in app
* GubGhz: KeeLog: add Save, Load key, key generation from the serial number of the meter and the button
* SubGhz: format sources and fix compilation
* FuriHal: add subghz configuration description for AGC section
* SubGhz: save only protocols that can be saved. Cleanup.
* Github: lint on pull requests
