Deprecation warning with numpy 1.20
https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
/users/valls/workspace/bliss.git/bliss/scanning/acquisition/calc.py:8: DeprecationWarning: `np.float` is a
deprecated alias for the builtin `float`. To silence this warning, use `float` by itself. Doing
this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type,
use `np.float64` here.
Deprecated in NumPy 1.20; for more details and guidance:
