and updating values (#98) * Fix writer copy constructor from reader config. * Extended tests for writer constructor changes. * Add copy of extents. * Update tests to fully test copy from reader to writer. * Update CHANGELOG.md. * Clean-up code and add python tests. * Update CHANGELOG.md. * Review clean-up. * Fix python test. --- CHANGELOG.md | 4 ++ cpp/include/copc-lib/copc/config.hpp | 17
