enh(io): move csv reader from io::dicom to io::base
Description
A generic csv reader is available on sight::io::dicom. Since it is a generic class it could be useful to mutualize it outside dicom field (in io::base for example ?)
Proposal
Move csv reader from sight::io::dicom to a more generic lib.
Outcomes
Mutualize the csv reader, and don't link against dicom stuff.
