Add "Microscopy" as the outermost folder

[ssomnath]

ScopeReaders shouldn't necessarily be limited to microscopy (though the name partly suggests as much). We should add a directory called "Microscopy" above all the SPM, EM, etc. that we have. This will make room for other communities like mass spectrometry, etc.

Importantly though, should we consider renaming this package to something more general / accommodative?
How about ScienceReader, ExperimentReaders (potentially, this could be used for extracting information from simulations too), SciFiReaders (scientific file readers) or something better?

In order to be more inclusive, we have decided to rename this package to SciFiReaders.
