Failsafe match for processing files

[zeromous]

Needs failsafe - if file it is processing for any reason size or attributes do not match of file it is replacing, an error should be thrown and move to next file

[zeromous]

Needs demonstration on how this could happen.

Create for different images:
IMG_000000.jpeg
IMG_000000.jpg
IMG_000000_--_.jpg

Observe what happens. Ensure all three images survive process.

result of 3 different files with similar names as described above, each with different meta data:

next test is with 3 different files, similar names, and the SAME metadata:

🔴 Note it in fig 2b did not count skipped file
🔴 Note it in fig 2b did not count skipped file
seems like safe result though, both files preserved, file conflict rejected by shell, original file preserved untouched.

next test with 3 different files with similar names as described above, but no meta data just different filesystemdata.
