New features

• Support for variable-sized chunks was added (#92)
• Added support to encode and decode data chunks without reference to a LAZ file.

API Changes

API changes in the support code are substantial.

• lazperf::reader interface has been moved from "io.hpp" to "readers.hpp"
• lazperf::writer interface has been moved from "io.hpp" to "writers.hpp"
• Moved header support from "io.hpp" to "header.hpp"
• Added chunk_compressor and chunk_decompressor to allow manipulation of LAZ data chunks without reference to a file.
• Added writer::basic_file::newChunk() to create a new data chunk when writing points.
• Added writer::basic_file::firstChunkOffset() to return an offset to the location where the first chunk should be written.
• Header support for versions 2-4 has been altered. The API works with a LAS 1.4 header, some of which may be zero if the file version is 2 or 3.
• VLR support has been modified to allow simple reading from or writing to an open stream.
• All data is now properly set to little-endian when written and converted from little-endian when read if necessary.
• Added ChunkDecompressor emscripten binding to provide access to the C++ chunk_decompressor class.

Resolved Issues

• An assertion that could be raised when encoding INT_MIN has been fixed. (#94)
• An error in decoding some fields where no change existed in a chunk has been fixed. (#95)
• An assertion raised when decoding files with more than one chunk has been fixed. (#96)
• A bad check on compressor type in the LASzip VLR has been fixed. (#100)
