Xiegu X6100 buildroot

External buildroot tree for the Xiegu X6100 transceiver.

Current release: 20260625

What's new in 20260625

• rade_demod_wav: OFDM demodulation (rade_rx) and vocoder synthesis (fargan_synthesize) now run concurrently on separate cores via a producer-consumer pipeline, reducing decode time for a 49 s file from ~61 s to ~39 s (~1.6× speedup, faster than real-time).
