Title: ENH Added file path existence check for read_hdf

ENH GH7715

Added simple check for file path existence. It might be more advisable to deprecate this function and separate file buffer and file path read functionality, but the current form matches the rest of the API.

I wasn't sure if there was any tests I needed to add, but if there is, let me know.
