New LF-RFID app (#534)

* Hal lfrfid: add read timer pulse and period config fns * New debug application for lfrfid subsystem * New lfrfid: app, fix naming * App lfrfid: assets * Container view module * App ibutton: remove unused header * App lfrfid scenes * App notification, add yield to blocking operations, add speaker volume control * App lfrfid: reading key scene * Assets: placeholder icon * App lfrfid: reworked container view module * App lfrfid: new scenes * App lfrfid: write scene * App lfrfid: write hid * App lfrfid: emulate scene * App lfrfid: save name scene * App lfrfid: add missing file
