Filled line charts

[yashovardhan99]

Just an idea. I was trying to make my own charts in compose and took some inspiration from this library.
I actually implemented a Line chart with a custom fill color/gradient. Is that something you have planned? Or I can try working on this with your library.
This is how my chart looks (custom gradient fill with a dashed line):-

Though note that I am not allowing an x offset (only y offset within the lines) in my chart. So I am not sure how to handle the fill with an x offset (as you have in your example).

Feel free to fork or create PRs for this, either one will work :)
