  [filter] IMU prefiltering using the One Euro filter

One Euro filter is a very simple adaptive low pass filter that can
efficiently remove the noise from the gyros and accelerometers without
adding to much lag.
As it is a separated module connected to the ABI bus, it can be used
with any IMU and AHRS/INS combination by selecting the correct data
source for the estimation filters.
