Ryan Malloy 5710584267 Add custom FX2 firmware and RAM loader for open-source development ...

Custom firmware (SDCC + fx2lib) implements all stock vendor commands
(0x80-0x94) plus new commands for spectrum sweep (0xB0), raw BCM4500
register access (0xB1/0xB2), and blind scan (0xB3). Compiles to 6.3KB
of code with healthy RAM margins.

RAM loader (fw_load.py) uses the FX2 0xA0 vendor request to load
firmware into RAM without touching EEPROM -- power cycle restores
factory firmware. Supports Intel HEX and raw binary formats.
