some numpy dtype types were missing from the NumpyScalarArrayMarshaller

[danielhrisca]

Some of the numpy scalar types were missing. This resulted in error messages such as the following

File "D:\TMP\myapp_venv_3.9\lib\site-packages\hdf5storage\__init__.py", line 1676, in savemat
    writes(mdict=mdict, filename=file_name,

because the input array had the typer numpy.uintc which was not found in the mapping.
