RawSubFile support multi file access (#173)

This PR is a fix/improvement to a problem that Jonathan had. (#156) The
original implementation opened all subfiles at once witch works for
normal sized datasets but fails at a certain point (thousands of files).

- This solution uses RawSubFile to manage the different file indicies
and only opens the file we need
- Added logger.h from slsDetectorPackage for debug printing (in
production no messages should be visible)
