Happens intermittently and irregularly anywhere between 1 and a few hundred milliseconds at a time. Throughput issue perhaps?

Yep, this is a throughput issue.

For whatever reason, the fatfs sync slows down intermittently to such an extent that the ringbuffer overflows. Some mildly clever changes to how long we wait between syncs and downsampling the attitude estimation to 100 Hz seems to help.

Adapted from old control firmware, so written in C. Pretty sure this one works,
however, unlike my previous "new" attempt.

Rocket flights are useless without data integrity. This is critical to address now that hardware integrity is being nailed down.

This will be resolved with the work in #46.
