Feat add parser

[pepoviola]

Add a pest based grammar parser, integrated through wasm by the module zombienet-dsl-parser-wrapper. In order to ingrate the new parser I made a couple of changes of the internal interfaces:

• cli -> now reads the dsl file and run the nunjucks replacements and parse it to the new TestDefinition interface.
• test-runner:
  • now takes the config base path, the test name and the TestDefinition as parameters
  • Assertions and commands now lives in a separate files and the testFn is generated from an internal registry of funcion generations.
• types.d -> Several types we added.

Also, the parser crate includes a cli that take the dsl file as input and parse it to the json representation. We can explore use it in the vscode extension to validate the dsl since produce a nice output thanks to pest :)

Super nice, a few small~ish nits, mostly around unwrap and a few too many integer types, other than that - hell yeah 🔥

Sorry for the huge amount of suggestions. They are more of "shortcuts" and minor corrections than rather anything huge that would block the PR. (Also I think you need to run lint)
