You must follow the same instructions as in the first subject but this time with colors.
The output should manipulate colors using the flag --color=, in which --color is the flag and is the color desired by the user. These colors can be achieved using different notations (color code systems, like RGB, hsl, ANSI...), it is up to you to choose which one you want to use.
* You should be able to choose between coloring a single letter or a set of letters (use your imagination for this one).
* If the letter is not specified, the whole string should be colored.
* The flag must have exactly the same format as above, any other formats must return the following usage message:
* git clone git@git.01.alem.school:AidanaErbolatova/ascii-art-color.git
* write command - go run . something --color=<color>
