[PATCH] support latitude of natural origin for Transverse Mercator projection

Description

Our implementation of the Transverse Mercator ignores the latitude of natural origin parameter (+lat_0=*) and assumes a value of 0.

Many Transverse Mercator-based projections require a value different from 0, so we should use an algorithm that supports it.

Attached is a replacement copy&pasted from the Geotools project (who copied it from proj.4).
