Possible redundant files in the submodule source

[icp1994]

This is the current set of files inside the zipped submodule source

3rd/
ci_staging/
doc/
locale/
log/
luamake/
make/
meta/
script/
test/
tools/
changelog.md
debugger.lua
LICENSE
main.lua
make.lua
README.md
test.lua
theme-tokens.md

I think 3 of these - ci_staging, log, and luamake are unnecessary for building from source but I'm not totally sure.
