add a metadata structure for the hex transform

the structure will eventually be populated from a few places, but for now, the proof-of-concept installs a complex hook that runs only on the call to "allocate" done at the top of "label-loop".

the comment output code works: the metadata entries are output in the appropriate places in the dump! yay

Force-Push: yes

   There is not yet a recommended way to run the hex transform on evoke.e, but
 when there is it will look like appending most of the Evocation-in-Evocation
