Support for rgba within cm-colors

[kylowren85]

Problem

Need rgba(r, g, b, a) support in cm-colors, for tune_colors function.

Context and Considerations on what needs to be done

1. Either conversion of rgba() into rgb() as an aftermath calculation that considers the background color and the text color, i.e., background color affects the text color if text has alpha channel (rgba), so cm-colors should have a function that finds the resultant color of the text with rgba that is affected by the specific background color (of course, a text with transparancy and a bg color will have a color thats inside the color spectrum).
2. Or have a completely new algorithm that takes in alpha channel into consideration while tuning colors, so cm-colors uses one method for non alpha colors, while uses a different method for colors with opacity.
3. Or any other method you may feel works best while adding rgba support.

Solving this issue helps what?

It helps in reworking CLI tool of cm-colors, where css parsing currently ignores rgba colors. The CLI needs cm-colors to have a way to tune rgba colors so that the parser can tune them also and output css files.

What does the CLI do, why should I care about that with this issue

The CLI parses entire css file, which may contain rgba values, and output an entirely new css file with tuned colors wherever possible.
At present theres no support for rgba from the CLI side, the CLI simply ignores it and writes the output file without tuning whatever color was defined with rgba

So more info on what needs to be done,

Currently, we take either a string or tuple input for hex / rgb support and then parse it through the parse_color_to_rgb() functio,n and it returns whatever the input is, as to rgb tuple

But we don't have support for rgba color space yet, so

1. Create a rgba_to_rgb() function under conversions.py that correctly converts and returns the tuple in the required format
2. Update parse_color_to_rgb() to recognize if it's an rgba string (CSS convention ) or just the tuple with 4 values. We need it to redirect the pair to the helper function for it to convert to the standard RGB tuple format
3. Make sure to add relevant tests under tests/ folder
4. Also run the existing test suite and mention if it passes in the pr

You can always make Pull Requests without asking for it, for the Pull Request itself is a form of asking the authors to accept your code.

Hii, great job working on it!! You can always make a pull request once you are done with the work, it's just a way for us to see if it fits and we could work together to solve if anything needs changes :>

I will look into your pr soon - I am so proud of you for taking this step forward
