[FL-2045] SubGhz: new protocol (GSN , Beninca/Allmatic, Elmes) and validator (#958)

* SubGhz: add new method of obtaining a manufactory code subghz_protocol_keeloq_common_magic_xor_type1_learning
* TextInput: checking for a lock on a file with the same name
* TextInput:  fix checking for a lock on a file with the same name
* Assets: rename and recompile
* TextInput: added picture and timer to turn off blob
* TextInput: Fix graphics
* TextInput:  fix validator
* Validators: Add validator is file
* TextInput: fix callback validator_is_file_alloc
* SubGhz: add propocol GNS (dimamic), Beninca/Alcatic,  Elmes
* SubGhz: fix function description
* Gui: correct timer routine on deallocation
* Format sources
