digital/chunks to symbols: be less inefficient
The block formerly took the tags from get_tags_in_range (which are
sorted), gave them to tag_checker, which sorted them, and then went
through every input sample, checking its index against the next tag.
Removed the tag_checker; that saves us a sorting of a sorted vector.
The other optimization is to not dispatch any tag encountered to the own
message handler; instead, the handler is called directly.
