Detailed Description

IIO transmit streaming thread for the ADALM-PLUTO.

Owns its own iio_context connection (cf-ad9361-dds-core-lpc) separate from PlutoCtrl and PlutoRX. The Pluto hardware runs at 2.5 MSPS (4× the SoDaRadio IF rate of 625 kSPS). Incoming 625 kSPS CBufs from RadioTX::run() are accumulated in a vector; once enough samples are available, SoDa::ReSampler interpolates 4:1 to 2.5 MSPS and the result is pushed to the Pluto DAC via iio_buffer_push().

The DDS tone generators on cf-ad9361-dds-core-lpc are disabled at construction so that our streamed samples reach the DAC unmodified.
