## Description

WIP, A straitforward translation from OGC Features and Geometries Json (https://docs.ogc.org/DRAFTS/21-045r1.html) to ATProto lexicon, following the draft lexicon styleguide. The most distinct change is the representation of coordinates as integers (#float64) defined as and an optional integer coordinateExponent (#float64exp) and type renamed to Lexicon $type
