Add epsg service

[hwbllmnn]

Description

This adds an /epsg endpoint that can be used as an alternative to the https://epsg.io API. Example: /epsg?q=EPSG:25832. Please note that this adds a dependency to GeoTools 33-SNAPSHOT as it needs unreleased functionality to produce the proj string of the coordinate system.

Also adds an /epsg/transform endpoint that can be used to transform WKT geometries from one crs to another. Example: /epsg/transform?source=EPSG:4326&target=EPSG:25832&wkt=POINT(45%207)

Looks great, can you add some tests maybe?

Done, I've also added another endpoint to transform WKT geometries.
