Tokenizer doesn't handle > needed for child combinators

[elcritch]

Thanks for the project! I'm getting a bug using the tokenizer and it not handling > properly.

I'm trying to parse child combinators like:

    const src = """
    Button > directChild {
    }

    Button > directChild.field {
    }
    """

    let tokenizer = newTokenizer(src)

    while not tokenizer.isEof():
      echo repr tokenizer.nextToken()

This just prints Token(kind: tkIdent, ident: ">") forever.
