[#558] Add Range type to Lorentz

I still intend to add some tests.

Description

What it says on the tin.

Additional effort was spent on this condition from the issue description:

error messages on type mismatch remain neat, they should not be like Cannot match 'Natural' with 'RangeInternal 'RangeInclusive 'RangeExclusive'

Ultimately, hiding "ugly internals" with things like TypeErrors can work in some cases, but generally it hurts type inference due to use of incoherence. Thus, "ugly internals" are hidden behind newtypes instead.
