Fix "double inversions" in pipelines, require a defined forward operation.
"+proj=pipeline +inv +step +urm5 +n=0.5 +inv" now works as expected, returning the forward operation of urm5. In principle adding more +inv's should also work, resulting in the forward operation when an even number of +inv's are present, and the inverse when an odd number of +inv's are present. "+proj=pipeline +step +urm5 +n=0.5 +inv" fails at initialization since no forward operation can be performed. This is a new requirement, but aligns perfectly with the rest of the library since no operation without a forward method exists.
