Workaround for Capture startup hang (#1285)
* Attempt to fix Capture startup hang

* Pump baseband_queue on M4 startup

* Synchronization experiment

* Moved SpectrumCapture member, better hang detection for M0

* Prevent execute from working on members until class has been initialized.

* Formatting

* Remove workaround.

* Rebase on next
