Widen ERT baseband filter to 2.5MHz.

Push packet timestamping earlier in packet handling.

Ideally, it'd get pushed back into baseband, and baseband would correct for the length of the packet (based on preamble/access code match timestamp minus preamble/access code duration) to give the exact time the packet started.
