An ANSI color library for V. (Vlang)

This is a very simple library that provides some functions to print out colorful strings to the terminal. ANSI colors work on UNIX-like operating systems. I am not sure if Windows supports it. You can see for yourself: Wikipedia

Functions in this library returns strings that are prefixed with appropriate color codes and that are suffixed with a reset color code (so, you don't have to reset back to default terminal color).

Some examples

    import ansicolors as a

    a.bg_black("hello")

    import ansicolors as a

    println(
        a.fg_black("hey ") + 
        a.fg_blue("how are you, ") + 
        a.fg_bright_yellow("today? ") + 
        a.fg_bright_magenta("I hope you are doing fantastic!")
    )

    import ansicolors as a

    println(
        a.bg_bright_yellow(
            a.bold(
                a.underline(
                    a.fg_bright_red(
                        "hello guys :D"
                    )
                )
            )
        )
    )

    import ansicolors as a

    println(
        a.bold(
            a.strikethrough(
                a.fg_bright_blue(
                    a.bg_bright_white(
                        a.italic(
                            "I am glad, I found you."
                        )
                    )
                )
            )
        )
    )

Yes.

The implementation is so repetitive, and it is quite possibly an unmaintainable codebase. But fortunately, I am not going to be actively maintaining it, as the library has no potential to grow. And the codebase is quite small, so, no worries!

I was bored, and I was interested in V.
