untilTag breaks if the tag is not in dicom

[Djeisen642]

I've tried out the latest dicomParser, and I'd like to suggest using >= instead of ===. That way when the parser reaches a tag after the tag asked for, it'll stop. Otherwise, I seem to run into some kind of buffer overrun. That also may need to get fixed. If it can't find the tag and it finishes reading the file, it should stop trying to find it.

I would also very much appreciate this :)
