Add ColorLike type alias

[njourdane]

Creating a type alias like this:

from typing import TypeAlias
ColorLike: TypeAlias = (
    _.Color | # build123d color
    _.Quantity_ColorRGBA | # OCP color
    str | # name, ex: "red"
    tuple[str, int] | # name + alpha, ex: ("red", 0.5)
    tuple[float, float, float] | # rvb, ex: (1, 0, 0)
    tuple[float, float, float, int] | # rvb + alpha, ex: (1, 0, 0, 0.5)
    int | # hexa, ex: 0xff0000
    tuple[int, int] # hexa + alpha, ex: (0xff0000, 0x80)
)

and a convertion method like this:

class Color:
    @classmethod
    def from_color_like(color_like: ColorLike) -> Color: ...

and replacing Color method parameters by a ColorLike might be practical.

It will allow for instance this syntax:

obj = Solid(obj=box.wrapped, color="red")

Instead of explitly instantiating the Color object:

obj = Solid(obj=box.wrapped, color=Color("red"))

I can create a PR if you agree.

Yes, a PR would be welcome, thanks for this - it reminded me to change over VectorLike and RotationLike to TypeAlias. The constructor of Vector and Rotation take VectorLike and RotationLike respectively so the constructor of Color should take ColorLike.

I need to spend some time with the docs so the APIs just show these "like" types and not the exploded values.
