Library to read Matlab files

[gmaze]

I see that pyowc is using 2 libraries to read Matlab mat files:

• pymatreader read_mat
• scipy.io loadmat

The former is used only once, the latter basically everywhere else.

I see from #52 that pymatreader was added to fix #30 , so in fact we can't get rid of this dependency

So why using 2 dependencies for the same task ?

Should pyowc use only 1 reader ? pymatreader only

ps: This is not considering the fact that all external data should be accessible in other formats than Matlab (eg: #53)

the pymatreader has been used to be able to read some older versions of the Matlab files.
I think that yes the pymatreader might be used in the code instead of scipy.io
