New: A GNU Radio out-of-tree (OOT) module implementing packet radio protocols including AX.25, FX.25, and IL2P.

Features
AX.25 Protocol

    Complete AX.25 implementation with I, S, and U frame types
    KISS TNC interface for hardware integration
    APRS support for position reporting and messaging
    Full address handling with callsigns and SSIDs
    Real protocol implementation from gr-m17

FX.25 Support

    Forward Error Correction (FEC) for AX.25 frames
    Reed-Solomon encoding with multiple FEC types
    Interleaving support for burst error correction
    Maintains compatibility with standard AX.25

IL2P Protocol

    Improved Layer 2 Protocol implementation
    Reed-Solomon forward error correction
    Enhanced reliability over noisy channels
    Modern replacement for AX.25

It has been fuzzed, and it compiles.
