avoid repeated scanning of the metadata entries during formatting

there was a test that had never been working, meaning the entire entry array was being scanned for every byte of output. even had that test worked, it would still have scanned on average half the array for every byte, so that'd be where the absurd runtimes were coming from. anyway, it works now.

this gets a full hex transform invocation down from over thirteen minutes to under thirty seconds. learn your data structures and algorithms, kids.
