pt3_lib: update to generate the four frequency tables on the fly
...
probably makes the executable a bit bigger but good for correctness sake
only generating the v3.4+ tables. Would be fairly easy to add the four
3.3 versions, but in practice I don't see many files of that type

pt3_lib: fix issue where vibrato was broken
...
backed out a qkumba optimization that in retrospect I am not sure
what it was doing but it was broken subtly in at least 2 places
could probabl be re-optimized again, especially the pt3_lib version

was playing OOTW ending wrong
was an accidentally commented out "lda #0 " blurgh
some other code cleanups while at it, mostly making it match
the pt3_player code a bit more
also stop using TEMP from interrupt as other code might use it

also added a lot of extra init-to-zero so the validation tools

pt3: init zeroed vars with loop
...
switching songs, sometimes they'd start wrong due to vars not
being initialized. Easier to just zero everything than try to
figure out which field we weren't getting. Also makes code smaller.
