Search by commit instead of dates

[flacle]

Search by commit would probably be optional arguments.

• There are two arguments, start and end commit hashes.
• Search by default is the short hash, any hash longer than this gets truncated to its short version, any hash shorter than this gets an error message.
• If the timestamps of the start and end commits are not in order (reversed, equal) then the order has to be fixed, in case the same commit is used for both start and end date then the git command should just take one hash.
• The optional commit arguments should override the positional dates arguments.

If it's ok for you I'd like to try to solve this issue

@JonathanGuerne great, any help is appreciated. Would recommend though to keep the scope tight, any new issues/requests that you stumble upon can be solved via separate issues, this makes review/testing more efficient. Perhaps after the release I can help with #9, this will make the codebase more friendly to include in other workflows/pipelines.

I submitted a PR (https://github.com/flacle/truegitcodechurn/pull/12) As you asked I focused only on the issue mentioned here.
