SplitLayouts don't work correctly in some cases

[rock3r]

As pointed out by @YasserDbeis, in some cases the SplitLayouts don't work correctly when dragging the divider. This can be caused by a bad combination of initial divider position, min, max and width. The fix is probably to change the API to not mix ratios and actual positions.

I'm considering rewriting the split layouts based on the core logic of Accompanist's TwoPane component
