8bf16e677f ffv1enc: allow encoding with 1 slice for CIF and smaller in version 3 
the default is still 4 slices for any resolution, this just allows the user
to force 1 slice.
This in my quick test improves compression by 1% for a 320x240 sample

e4255eaf47 ffv1: split decoder and encoder 
This is not based on lucas work due to code divergence (its less work this way
than trying to merge from a split based on 2 years outdated code)
