Maintenance/fix numba warning
Fixes:
/builds/EnMAP/sicor/sicor/AC/RtFo.py:24: NumbaDeprecationWarning: The keyword argument 'nopython=False' was supplied. From Numba 0.59.0 the default is being changed to True and use of 'nopython=False' will raise a warning as the argument will have no effect. See https://numba.readthedocs.io/en/stable/reference/deprecation.html#deprecation-of-object-mode-fall-back-behaviour-when-using-jit for details.
@jit(nopython=False)
Fixes #104 (closed).
