Start working on improving test coverage (#1424)

kdt3rd · web-flow · commit a00bac506f69 · 2023-05-21T09:28:06.000+12:00
* fix potential crash
* Add initial tests for half utility operations in core
* add dump of attr to support testing of debug code (coverage)
* Add simple script around running and generating coverage report locally using clang tools
