Add `Relude.Numeric` module with `integerToBounded`

[chshersh]

This should solve specific use case of #114 Specifically:

1. Move all number-related reexports and functions in this module.
2. Add integerToBounded function:

integerToBounded :: forall a. (Integral a, Bounded a) => Integer -> Maybe a

3. Add integerToNatural function there:

integerToNatural :: Integer -> Maybe Natural

4. Reexport toIntegralSized:

I'd like to work on this if it's ok :)
