Switches readLas/writeLas and LasWriter from libLAS to the laszip_api.h C API, adding LAS 1.4 support (formats 6-10 and 64-bit point counts) and replacing the legacy DataFormatId bit-mask checks for time/colour. Updates the build to find LASzip 3.x and drops libLAS from the devcontainer.
- README: replace libLAS + LASzip 2.0.1 build steps with a single LASzip 3.4.4 instruction, note LAS 1.4 / COPC support. - docker/Dockerfile: drop the libLAS build stage, bump LASzip to 3.4.4 and build it Release. - .devcontainer/Dockerfile: build LASzip in Release (unoptimized builds make LAZ decompression 5-15x slower). - Remove the now-unused cmake/FindlibLAS.cmake module.

Replaces the unmaintained libLAS dependency with the LASzip API
Adds support for LAS 1.4 (point formats 6–10 and 64-bit point counts) so rayimport can read modern .laz files including cloud optimized point cloud (COPC).
