workaround for rounding us/iter
...
for some reason rounding is giving me wrong results
not sure what i'm doing wrong :D
just show 6 digits :P
ok this gets the us/iter working, and it is more stable
but the elapsed time still needs to be added

wip changing time units
...
it does this weird thing where sometimes it's reading out wrong digits
and then switches to expected unit of sec/px
work in progress no clue what's going on

move total_ms, total_pixels out of zero page
...
this frees up 12 bytes of zero page space and costs no measurable
time as these variables are not in the hot path and there was only
a tiny bit different.

apply jamey's suggestion of skipping add for high byte muls
...
rather than saving 0 into the high bytes, then adding the high-byte
multiplication later, write it directly in place. this saves a few
cycles on every iteration, and it adds up nicely.

Faster pixel skipping on 4x4, 2x2 tiers
...
Iterate at fill_masks[fill_level]+1 instead of every pixel and then
skipping, saves a smidge of time
