Native (X, Y, Z)-axis offset subtracted from each decoded coordinate
in f64, BEFORE narrowing to the Float32Array (extends #1804's
LAS/LAZ pattern — see decodeLasPoints's originOffset doc). Some
PCD exports carry absolute survey/map coordinates at ~1e6-1e7 m
magnitude, which quantise to sub-metre noise once narrowed to f32
without this. undefined (the default) subtracts nothing, preserving
prior behaviour byte-for-byte.
