d9bfaaf805 Stop baseband streaming when switching radio configuration.
Probably unnecessary, but feeling paranoid about changing sample rates while there's a processor actively handling samples, and potentially maxing out the M4 core.

0647f26707 Move SGPIO configuration and control to baseband firmware.
Addresses long-standing and annoying bug where SGPIO DMA channel would not disable -- and not configure cleanly next time it was needed. My theory is that the DMA channel couldn't disable until it got a request from the peripheral, and sometimes the peripheral was disabled before that last request.

Anyway, the baseband firmware should control the SGPIO, methinks, despite the impact on baseband code size.

82ff45860e Add basic ERT (OOK) utility meter reception.
Extracted the Manchester formatting function for use in ERT, now also returns an indication of bits in error.

5d9079f87f Stop streaming when changing baseband configuration.
Without, the baseband would get confused.

45d26abf10 Use correct memory region for persistent storage.
Turns out 0x10088000 - 0x10089fff is not the right place. It's 0x40041000, and is only 256 bytes!
Move PPM to correct place, change representation to PPB for finer control.
Reset PPB value to initial value if read value out of bounds.
Clip PPB value on write to permitted bounds.
Contributes to resolution of issue #11.
