* Core: wipe memory after free. RFID,iButton: fix iterator use after invalidation. * Debug: support unix wildcards for register matching in svd, update MCU description file and minify it. * Toolbox: getter for File in FlipperFile. * Makefile: conditional flashing * SubGhz: keeloq_mfcodes encryption tool. * FuriHal: proper IV handling on CBC in crypto. SubGhz: add support for encrypted keeloq keys. Makefile: move formatting to top Makefile. * SubGhz: rename some function names to match naming scheme. * SubGhz: encryption tool, fix windows line endings Co-authored-by: DrZlo13 <who.just.the.doctor@gmail.com>
