[META] Ideas 💡

[moul]

• analyse the strange behavior detected on zrwf + add a unit test
• only print paths instead of deleting (feat: switch to print-only instead of removing #5)
• add a flag to print the opposite list (--keep)
• add examples in the CLI help
• add --glob flag to specify if the paths should be matched or taken as they are + add examples in -help
• improve support of files with exact same timestamp
• support alternative way to get the date, i.e., by parsing the filename
