inverse does not check for inputs of special arrays

[scheidan]

For scalar transforms inverse is checking the input but not special arrays:

## scalar transform
inverse(as(Real, 5, 10), 5.5)
inverse(as(Real, 5, 10), 1.5)                  # -> error, good
inverse(as(Real, 5, 10), 15.5)                 # -> error, good

## array transform
inverse(UnitVector(3), [sqrt(1/3), sqrt(1/3), sqrt(1/3)])
inverse(UnitVector(3), [0.0, sqrt(1/3), sqrt(1/3)])      # -> no error, bad

inverse(UnitSimplex(3), [0.2, 0.2, 0.6])
inverse(UnitSimplex(3), [0.3, 0.2, 0.6])                 # -> no error, bad

Not sure if this is an omission or design decision.

No, this is an omission. I will fix it soon, by #65.
