[Proj] Add custom projection

[raul pra levis]

Hi Janne,
thanks for the response.
Our custom projection is an approximated Mercator Meter projection based on International 1909 ellipsoid.
The approx formula is:



y
= ln ( tan(1/2 * atan(tan(lat_rad) / 
1.0067642927) + PI/2) ) * 6378388.0


The choice of using an approximated projection is historical and related by hardware limitations of thirty years ago.

Regards,

Raul
