Fixed
- ISS SSTV stopped and froze during a pass when Doppler correction was on. Each Doppler retune restarts rtl_fm, and the decoder treated the old rtl_fm closing as a crash and shut down, so the Doppler status stopped updating and the page hung on its last message. The decoder now carries on reading from the retuned rtl_fm, and stops cleanly with an error if rtl_fm can't be restarted. (#438)
- SSTV pages hung when the decoder stopped unexpectedly. Both the ISS and General SSTV pages ignored the decoder's error message; they now show it and return to idle so you can start again. (#438)
