BG - Need a `Map Range` node

[j-conrad]

Is your feature request related to a problem? Please describe. It is common to want to be able to take a range of input values and remap them to a different range of values. For example, taking input values of 0-1 and remapping the output to 30-45. Or easily inverting a range of 0-1 to 1-0. This becomes even more useful with remapping vectors.

Describe the solution you'd like I would like there to be a Map Range node, which exists in Blender in various contexts such as Geometry Nodes or Shader Graph.

Here's the Map Range node set to Float vs. Vector:

Describe alternatives you've considered I've mimicked this setup using many Math nodes, but it is cumbersome and difficult to reuse.
