feat: add utils split_args function

[Diaoul]

Fixes #629, #816 and #1267

[Diaoul]

Not sure where to add unit tests 🤷

Nevermind, found it, it's just called "spec" in lua, how confusing..

[Diaoul]

Here are test results ran locally though:

{ [1] = runserver, [2] = --debug, [3] = true, [4] = --reason, [5] = I'm dumb } 
{ [1] = --comment, [2] = I'm "this" close }

[Diaoul]

Added some tests but I cannot run them locally, new to lua projects and I can't seem to have a working env.
I'll rely on the CI to iterate or if you can fix the CI issues that would be awesome (since CI needs your approval to run) 🙏

Do you have some good documentation about setting up a lua dev environment on Linux for Lua? I'm struggling with busted for some reason...

❯ luarocks --lua-version 5.3 test --local

Happy to have some help here to push this to the finish line when you have some time @mfussenegger 🙏

Thanks. I've made a couple of changes to add docs, simplify it a bit, and got rid of the failing scenario (nested escaped quotes inside quotes)

[Diaoul]

Very cool! Thanks a lot!
