| | This stops exposing eeprom as 'storage' and instead exposes it with a
separate eeprom API so that it can be used for config storage without
also using it for flight log storage.
The config code has been changed to allow it to either use storage for
configuration data or eeprom.

| | The range was cranked down at some point to diagnose issues within the
task scheduler. Unfortunately, that change got merged, which meant
that general profiling lost information outside of the lower 4kB of code.

| | Trying to compute the combined rotation by taking the x/y/z rotations
as a vector is a good approximation, but not accurate enough for our
application given the large angles we sometimes see.
Instead, use a correct-but-expensive function with a pile of
transcendental function calls. The STM32L seems to be fast enough at least...

| | This initializes the rotation with the angle from vertical, rather
than simply recording the off-angle vector. Doing this allows us to
accurately track the true orientation of the rocket, instead of just
the offset from the initial non-vertical orientation.

| | Our low sampling rate means that the "cheap" hack for
integrating quaternion rotations by using sin(x) ≃ x doesn't work, so
instead we have to compute the partial rotation the hard way.
