Build u32/u64 from raw bytes (R's readBin doesn't support signed=FALSE for size>=4) and silence seek() return values via invisible(). Smoke-tested against PDAL output: 2099 leaves, max_depth=5, total_points=45,243,335.
…iant and add writer filtering in run_writers
…ipts - Introduced a comprehensive report for validating LOD quality and seamless multi-tile merges in the experimental COPC writer. - Implemented edge-artifact checking for merged COPC files. - Created scripts for fetching adjacent USGS 3DEP tiles for multi-tile merge testing. - Developed a validation script for visualizing LOD across different depth levels. - Added functionality to merge multiple LAZ tiles into a single COPC file with specified density settings. - Orchestrated the entire validation process through a main script that coordinates all phases, including LOD validation, tile fetching, merging, and edge artifact checks.

Summary
Adds a reproducible benchmark harness for the experimental COPC writer
on top of
copc-multifile-merge. Pure additive — onlybenchmarks/copc/gets new files; no source code changes (those all live in the parent
branches).
