`z = 15` does not seem to always work #102

Not sure why (I did not debug), but when increasing z from 14 to 15, I get a strange error message. If z cannot go higher than 14 on some parts of the world, I think that a precheck may be helpful. This is vietnam, but it may happen elsewhere, I did not check (it happened today during a course).

                         prj = "+proj=longlat +datum=WGS84 +no_defs",
                         z = 14)
