Refactor render register file

[angelina-momin]

Made the following changes:

• Created separate functions for each register rendering and register checking utility in register.R
• Moved preprocessing utility functions to file utils_preprocess_register.R
• Moved rendering utility functions to file utils_render_register.R
• Moved register checking utility functions to file utils_register_check.R
• Added myself as an author in the DESCRIPTION file
• Bump version from 0.1.0.9005 to 0.1.0.9006 in the DESCRIPTION file
• Updated workflow file R-CMD-check.yaml to use r-lib's v2-branch instead of master branch. Otherwise the workflow runs fail. The "master" branch was replaced with "v2-branch"

Already tested it out by running the function and checking the results and it looks good.

@nuest I cannot add anyone as reviewer so I am tagging you here to ask for a review.

@nuest The checks are failing because r-lib/actions no longer has a master branch: link. Their default branch is now called "v2-branch". Should I update the workflow file and replace "master" with "v2-branch"?

Hi @angelina-momin !
Yes, please do update the workflow file as you see fit.

Changes look good to me, only one more thing: Can you please bump the development version to 0.1.0.9006 in the DESCRIPTION file, see https://github.com/codecheckers/codecheck/blob/master/DESCRIPTION#L3C10-L3C20
Also, your personal details are missing in the DESCRIPTION file.

Once you changes become more significant, I'm very open to make a decent version bump and proper release - let's try to not forget that.
