Subject: Add `diff_options` to parse Git diff options

In order to accept Git diff options on the command line, we need a way
to extract these from args.

Add a function to parse diff options. These were sourced from:

https://github.com/git/git/blob/675a4aaf3b226c0089108221b96559e0baae5de9/Documentation/diff-options.txt

The function loops through the input arguments and extracts all diff
options and their values.

Still needs some work to integrate it into `git-sugdiff`, but it
currently works as advertised.
