Remove "latt" from asdf
For consistency with other algorithms, let's standardise on an
interpretation where just using the centering information in combination
with the cell parameters, which is always necessary, doesn't qualify as
"cell-latt", only "cell-nolatt".
"Using lattice type as prior information" implies that asdf would behave
differently with cell-nolatt, if it were allowed, than with cell-latt.
It wouldn't. It just needs the centering to calculate the cell volume
correctly.
Note that TakeTwo, by contrast, would behave differently in this
hypothetical case, because it uses the lattice type to exclude certain
solutions by symmetry.
Mosflm allows all four combinations of no/cell and no/latt, and does
indeed behave differently between them.
