LazIO

Extends LasIO with LASzip integration.

Uses the LASzip shared library to read compressed las files (*.laz) into the uncompressed format that LasIO reads natively.

julia> using LazIO

# Load header and all points
julia> LazIO.load("test/libLAS_1.2.laz")
(LasHeader with 497536 points.
, Vector{LasIO.LasPoint0} with 497536 points.
)

# Load header and range of points
julia> h, p = LazIO.load("test/libLAS_1.2.laz", range=2:10)
(LasHeader with 497536 points.
, Vector{LasIO.LasPoint0} with 9 points.
)

# Open file and iterate over points (streaming)
julia> ds = LazIO.open("test/libLAS_1.2.laz")
LazDataset of test/libLAS_1.2.laz with 497536 points.

julia> sum = map(Int32, (0,0,0))  # Int32, not yet scaled and offset
julia> for p in ds
           global sum = sum .+ (p.X, p.Y, p.Z)
       end
julia> sum ./ ds.header.number_of_point_records
(3497.988658107152, 3741.789882541163, -164.49942114741447)
