Additional PSNR evaluations for the normalized synthesis case

[FelixSteinbauer]

As we normalize the data to [0;1], we have top-down knowledge now about the data range. For this knowledge I added two cases/columns of PSNR evaluations.

Proposed Changes

• Added psnr_01 and psnr_01_eps evaluation (psnr with data range of 0 to 1. With and without epsilon)
• Added/removed/changed comments respectively

This PR should be very minor, but relevant for the in-painting-chellange.

Checklist

• I have read the CONTRIBUTING guide.
• My PR is based from the current GaNDLF master .
• Non-breaking change (does not break existing functionality): provide as many details as possible for any breaking change.
• Function/class source code documentation added/updated.
• Code has been blacked for style consistency.
• If applicable, version information has been updated in GANDLF/version.py.
• If adding a git submodule, add to list of exceptions for black styling in pyproject.toml file.
• Usage documentation has been updated, if appropriate.
• Tests added or modified to cover the changes; if coverage is reduced, please give explanation.
• If customized dependency installation is required (i.e., a separate pip install step is needed for PR to be functional), please ensure it is reflected in all the files that control the CI, namely: python-test.yml, and all docker files [1,2,3].

Thanks! 👍🏽

Can you put the comment before the line that it represents for readability? Basically, instead of this:

overall_stats_dict[current_subject_id]["psnr"] = peak_signal_noise_ratio( #torchmetrics PSNR using "max"
                gt_image_infill, output_infill 
            ).item()

You put this:

#torchmetrics PSNR using "max"
overall_stats_dict[current_subject_id]["psnr"] = peak_signal_noise_ratio(gt_image_infill, output_infill).item()

And then run black.
