v0.11.0-rc1

This release is contains significant changes to quicksilvers flight characteristics,
with some of of them being in development and flight testing for literal years.

changes since 0.10.5:
add a dynamic notch filter pass to the gyro pipeline. a sdft algorithm is used to precisely track noise peaks in the gyro signal and then insert notch filters at these frequencies.
add a very simple cooperative scheduler to divide compute heavy tasks (like dynamic notch) across multiple loops.
optimize floating point accuracy of the angle mode pipeline
include yaw in stickvector calculation to increase accuracy at extreme angles. (thanks @Quick-Flash)
various performance optimizations
add crosshair osd element (thanks @TieuLongHo)
fix error vector rotation equation (thanks @DusKing1)

Profiles should all carry over, but please re-verify.

With the dynamic notch filter active, you will most likely need to re-tune you craft.
Most of the changes have been in testing for quite some time, however they are still significant, so please proceed with caution.
