LightSail spin analysis

… at least this make doppler and spin analysis easier


RF field strength plot shows ~ 8.5 deg/s (June 11 02:10 UTC)

the most recent telemetry (which is a bit old now) shows rates of

X = 7.225000 [deg/s]
Y = -0.300000 [deg/s]
Z = -0.087500 [deg/s]

7 deg/s is rather fast, but not as fast as we saw pre-deployment
