* Change awk to grep, delete ZAPD files, gitignore elf

* Delete all the cfg files

* Fix memory leaks

* Rename and add coloured errors

* Makefile tweaks
- preprocess spec before grep
- split order prerequisites via phony target to reduce dependency edges
- remove `resources` target
- remove separate overlays targets
- use `$(SPEC)` throughout
- change to using filenames of relocs for overlay names via `$*`
- Rearrange targets to better reflect their categories

* Update gitignore

* Review

* Add a check for the reloc file name

* get_segment_by_name

* get_stmt_id_by_stmt_name

* Cleaning up

* algorithm change

* function rename

* Fix typos
