Mvt
data class MvtFeature(val id: Long, val type: MvtGeometryType, val tags: IntArray, val geometry: IntArray)
One feature. geometry is the raw MVT command stream (interleaved CommandIntegers and ParameterIntegers, all as packed uint32s) — pass to MvtGeometry to materialise into lat/lon points/lines/rings. tags holds keyIdx, valueIdx, ... pairs that index into the parent MvtLayer's MvtLayer.keys / MvtLayer.values.
