rename videos set to video, multiple exts can be specified with multiple `-e` flags

CHANGELOG.md

@@ -7,9 +7,12 @@ Dates are given in YYYY-MM-DD format.
 - Added `-x`/`--exclude` flag for excluding file extensions (overrides `-e` or `-E` - `-E images -x jpg` scans all image
   files, except ".jpg" files)
 - Added `-X`/`--exclude-set` flag for excluding sets of files (like `-E`)
+- Both `-x` and `-e` can now be used like `-e jpg -e png` in addition to the existing `-e jpg,png` format
 #### Other
 - Published my fork of ['mime_guess'] as ['new_mime_guess'], allowing it to be used properly with
   [crates.io](https://crates.io)
+- The `videos` extension set has been renamed to `video`, in line with `audio`. `fif --help` has actually mistakenly
+  referred to the set as `video` since v0.2.12! 0uo
