Resolve incbin calculation errors in calcrom.pl

[WhenGryphonsFly]

This trims, sorts, and deduplicates the results of the incbin command; which resolves the overcounting that was previously displayed. I don't know why the command was finding duplicates; I only resolved the symptoms, not the cause.

Trimming (the awk command) is necessary; there are some lines that differ only in the number of spaces at the beginning of the line.

The runtime of calcrom did increase by about ~25%, so this may need an increase in the timeout if this takes substantially longer in the CI than on my computer.

I can be contacted at whengryphonsfly on Discord.
