I'd like to be able to run codespell on one or more specific files, rather than an entire directory. This would essentially have the opposite effect of -S/--skip.
The option should support filenames, directories, and blob patterns, all three as both a single argument and comma-separated lists. For example, if the option name is -f/--files:
codespell --files="foo.txt,bar.txt"
codespell --files="./some/folder"
codespell --files="*.md,*.txt"
