* SubGhz: changing the operation of the capture timer, and the logic of the work of parsers * Add toolbox lib. Move levels to toolbox. Subghz switch to levels. * Subghz: update worker signatures * SubGhz: pluggable level duration implementations. * SubGhz : test drawing pictures in Gui * SubGhz: Added a callback with the parser structure as argument * SubGhz: copy protocol data to model * SubGhz: refactoing code * SubGhz: cleanup and format sources * SubGhz: remove comments Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com> Co-authored-by: DrZlo13 <who.just.the.doctor@gmail.com>
