Description

Hi,

Is there a way to fill the area between two lines in UnicodePlots? Such as fill_between in matplotlib. image If not, how hard would it be to implement that function?

Research direction
Examine the existing plotting functions in the source code (e.g., src/lineplot.jl or similar) to understand how lines are rendered. Implement a new function `fill between` that takes two data series and fills the area between them with Unicode characters. Consider using similar logic to the existing `lineplot` function. Pay attention to overlapping and non overlapping regions to ensure correct filling.
