Pulls in the tui-rs grid logic so I can implement custom braille painting logic. We basically "flatten" the layering logic into a single layer by replacing resetting cells if the colour is different. This avoids the multiple allocations if we used multiple layers as intended with tui-rs. This gives us chart results similar to the current stable version, but with a flamegraph similar to the current master branch.
