rethought the rounding function

realized the top bits are not enough, that was a brainfart
doing comparisons now

no this seems right
...
but it's still coming out different. wtf am i doing wrong
it's gotta be a brainfart

sometimes wrong

ok two things wrong:

1) bit masks are backwards
2) iter always returning 0

flesh out the mandelbrot iteration loop
...
some bits i missed increased total to:
1939 - 3007 cycles per iteration
probably still buggy, will test later :D

Added two version of 16-bit rounding
...
round16_incdec uses inc and dec
round16_addsub uses adc and sbc
the incdec version is the same when no rounding is needed
but saves about 8 cycles on the rounding cases, for an
average savings of 4.5 cycles for randomly distributed inputs
untested so far
