[RE: JoSS Review] CS tag deconfliction

[betteridiot]

For the JoSS review at openjournals/joss-reviews/issues/6066.

The CS (uppercase) is a reserved for color read sequence information as per the SAM format, while the cs (lowercase)
tag represents the difference string. This has already been a topic of discussion while feature requests to incorporate the cs tag more
formally into the SAM format.

It might be beneficial to change the "CS" to "cs" in all documentation so as to not mislead users.

Thank you very much for your invaluable review!

I have implemented the change to lowercase 'cs', as you pointed out, in both the paper and the GitHub documentation (README and Docstring).

JOSS Paper:

d7c6cfb

Document (README and Docstring):
20dec8d

I would appreciate your confirmation of these changes.

This satisfies my suggestion. Thank you.
