Thetis compatibility

ThetisLink talks to the radio through Thetis. It targets Thetis v2.10.3.15 (the latest official release by ramdor) and works with stock Thetis out of the box. Optionally use the PA3GHM Thetis fork (branch thetislink-tl2) for the additional _ex TCI extensions used by ThetisLink v2.0.2 (capability broadcast, per-RX filter preset, diversity control suite, server-side DDC recenter, relaxed IQ-stream rate cap). All extensions are gated behind the ThetisLink extensions checkbox in Setup

Network > IQ Stream; with the checkbox unchecked the fork behaves like stock Thetis.
