refactor: remove rules

[Agustindeleon]

• Separate "remove" rules to generate independent events at the listener level
• Change int_range from a token to a parser rule in order to use the start and the end of range as integers

Looks good, haven't tested it myself.

Actually, could you please add a test for the modified functionality @Agustindeleon?

[theseion]

Add test for changed functionality

[Agustindeleon]

Actually, there are some simple test cases for these kinds of directives that ensure that the lexer and parser don't throw errors during their execution.

I know. But "no error" is not the same as "produces the correct output". The test coverage is still too low for my taste, and your change is a great chance to improve test coverage. The new test would also document the expected behaviour of the parser.

@Agustindeleon Can you add more tests somehow?

[Agustindeleon]

Hi @theseion @fzipi, can you take a look at the code and the test added? I think it would be a good idea to move all listener stuff to the new listener.go file, but maybe it's better to do that in a separate branch.

Good stuff!

I agree. Separate PR.
