feature: Add fill colors to render.Plot()

[betterengineering]

Overview

We support a line color, but not a fill color. This commit adds support for a fill color and an inverted fill color to override the alpha calculation.

Changes

• feature: Add fill colors to render.Plot()
  • This commit adds the ability to add a fill color to a plot to override the alpha calculation.

@rs7q5 you can now add a fill color to a chart. So a pink line and yellow fill if you so desire 😄 :

            render.Plot(
                width = 64,
                height = 24,
                data = data,
                fill_color = "#1C230D",
                color = "#95BF47",
                fill = True,
            ),

Awesome, although I'm hoping we can have alpha lines next too :D but this is a great addition!
