The uint16_codec argument for mne.io.read_raw_eeglab() is only used if the optional dependency pymatreader is installed. This PR adds support for this argument for the case when pymatreader is not installed and hence the base implementation via scipy.io.loadmat() is used.

Note that uint16_codec is an undocumented parameter of scipy.io.loadmat() (which is also used by pymatreader). However, since it seems to work in practice, I guess adding it should be fine.

This issue was originally reported in our forum here.

Thanks @cbrnr !

Bonus points if you want to open a quick (?) PR to SciPy to try to add this to https://docs.scipy.org/doc/scipy/reference/generated/scipy.io.loadmat.html as well

Sure, I can do that (I think just adding the parameter to the docstring section should be sufficient).
