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

#float64

integer

A float64 represented as an integer should be multiplied with the closest float64exp property in a context so a float64 of 314159265 and a float64exp of -8 would give a float number of 3.14159265
