• [x] remove skip_if_not_fileio_available(). This doesn't need to be deprecated. While it is exported (why?), it is a function that exclusively relates to the old directory structure of the hyperspec project.

This will remove lots of messages about skipped unit tests.

The unit tests themselves can still be looked up easily in the old hyperSpec repo at https://github.com/cbeleites/hyperSpec/

While it is exported (why?), it is a function that exclusively relates to the old directory structure of the hyperspec project.

Unit tests in other packages use this function. These unit tests must be updated/fixed.

[cbeleites]

Yes. Having this function in the other packages means that the unit tests were always skipped, so that needs to be fixed in the new packages.

[GegznaV]

The only package that uses skip_if_not_fileio_available() is hySpc.read.ENVI
