meta(cast): tracking issue for Cast improvements

From @Sabnock01:

Currently, `to-dec` and `to-hex` act as specialized versions of `to-base` making them both redundant.

These should probably be deprecated to remove clutter and simplify the tool and leave `to-base` as a catch-all for converting from one radix to another.

From @Evalir:

Cast right now would benefit from a better command structure and more docs. As an starting point:
