Does not obey --skip-if-exists. about unrarall HOT 2 OPEN

This seems relate to util selection, if I only install (sudo apt install) p7zip-full then the existing file is never detected, but when installing also (sudo apt install) p7zip-full unrar rar the detection starts working.

Seems related to function isAlreadyExtracted() and its utility selection.

As a sidenote, since skip-if-exists only does filename existence testing it is very inefficient to do chksfv before it (resulting in useless chksfv passes if nothing gets extracted).

FIY: I've attempted to do a more thorough comparison by extracting the filesizes from the archive and checking it against the extracted files:

It's not well tested so far, but should be a simple PoC for better file checking.

I also see that my files are not deleted, when I use the --skip-if-exists option -- might be expected, but I'd think I havew to force it?
