Geoparquet geoarrow conversion had previously been building a map with x/y/z/m entries for every coordinate read from the parquet file, then converting those to JTS coodinates when the geometry is requested. This change eliminates that wasteful conversion and has the parquet reader deserialize x/y/z/m values directly into a JTS
CoordinateSequence
.This also changes the reader to fail fast when parquet schema doesn't match what's expected for the primary geometry type.
