Type highlighting in `inspect_types`

Feature request

It'd be useful to highlight all the inferred types in the inspect_types output so that, especially on GPUs, accidental upcast of types is trivial to spot. e.g. float64 is red, float32 is orange etc etc.

I will look in to this and see what I can do.
