Fall through error in the binary operator for BasePoseMatrix #116
Description
Fall through error in the binary operator for BasePoseMatrix:
If you want to compare the rotation of an SE3 to an SO3, it returns none as opposed to throwing an error or returning a valid value. This should probably raise an error as opposed to returning None.
import numpy as np
from spatialmath import SE3, SO3
T0 = SE3()
print(T0.angdist(SO3()))
Could be fixed with closing else in BasePoseMatrix._op2
else:
raise ValueError(f'Invalid type ({right.__class__}) for binary operation with {left.__class__}')
