feat[PNCCD][Correct]: New corrected data source and link to legacy source

Description

• Write pnccd data in a separate data source and softlink to the legacy data source.
• Remove the stored raw image in */image/data and store corrected data in */image/data instead of */pixels/data
• Remove the stored gain map duplicated data from the corrected data files.
• Move from .../CAL/... to .../CORR/... by default to match other detectors.
