I know we purposely took out the airbrakes extension from the update() in coast phase, but I just added it back just so the test passes lol. We will obviously go back and change things once we do the control logic |
…ed-better-rotation Use `scipy` for rotations, improve performance of time differences by ~20%

Major changes:
Implementation of vertical velocity using rotated acceleration in the earth's frame of reference. This is more accurate than our current magnitude approach. However it is still slightly inaccurate during free fall by about 2-5m/s (just eyeballing it v/s altitude).
Apogee Prediction using curve fitting. This runs only for the duration of CoastPhase. We converge to true apogee with an accuracy of +/- 10m within 5 seconds of coasting.
The apogee prediction process runs only every 10 packets.
WIP:
plot velocity calculated from rotated frame vs speed from accel
