* [FL-3503] SubGhz: fix Handle rx buffer overflow
* {FL-3520] SubGhz: Handle RX buffer overflow with external cc1101
* [FL-3548] SubGhz: Security+ 2.0 counter start value
* [FL-3552] Sub-GHz: Check saved file
* [FL-3555] [FL-3554] Sub-GHz: RX buffer overflow handling and check that buffer has been properly written
* [FL-3557] Sub-GHz: No optimization required
* [FL-3558] Sub-GHz: Keeloq 0 discriminator
* [FL-3559] Sub-GHz: Keeloq unknown learning
* [FL-3560] Sub-GHz: callback for updating keeloq data on display
* SubGhz: fix RXFIFO_OVERFLOW
