Low Frequency Brute Forcer

One day this'll grow up into a real tool for LF RFID on the Flipper Zero.

For now it just lets you select an LF protocol and enter raw data to send, which is at least useful for enumerating through tag serial numbers.

It also crashes a bit.

TODO

• Hook up a debugger and see what's causing the NULL dereferences
• Load an existing savefile to seed state.data
• Less shitty UI
• Allow direct editing of FC/ID/etc fields rather than just the raw data, when I can be bothered reversing the render_data process for all protocols
