Range slider

[granthamtaylor]

I am very interested in using Textual to create a TUI for my AutoML project.

A common theme with model training pipelines is a large set of hyper parameters with seemingly arbitrary ranges.

I feel like a range slider widget would be an excellent way to provide context on recommended ranges for numerical inputs.

Ideally, the range would have formatting support, provide a tooltip when being updated, may be interacted with via both mouse and keyboard, and may provide custom range distributions (log scale, discrete, custom labels, etc).

I am curious if anyone else is interested in the idea!
