Tokenizer fails on protobuf metadata files

[roxblnfk]

Hi.
I'm encountering a tokenizer error when there are protobuf generated files in the project.

These lines:

tokenizer/src/Tokenizer.php

Lines 71 to 73 in abb3755

	$values = \preg_split('/\R+/Uu', $tok[1]);
	foreach ($values as $v) {

I var-dumped the $tok variable when $values === false and got this:

Looks like a Protobuf generated metadata e.g. this: https://github.com/buggregator/trap/blob/master/src/Test/Proto/Metadata/Message.php
