Rename OddLookupTable to NafLookupTable5.
An OddLookupTable corresponds to a non-adjacent form of width 5.

b0bda0278c Drop the stdsimd crate in favor of core::{simd, arch}.
This change required some work, because the to-be-stabilized SIMD functions
don't allow non-constant `imm8`s.  Previously, the `stdsimd` functions had a
constifying macro that ensured that the immediates were known.  The dalek code
used this to build helper functions which would be inlined into different
places where the immediates were known.  Unfortunately, since constexprs aren't
fully supported in Rust yet, this is done by a hidden compiler attribute, and
there's no way to propagate "constness".

To deal with this, some of the functions are specialized (e.g.,
`square_and_negate_D` instead of taking a mask), and others use an enum.
