- move generated vocab support from specialized-arrays to vocabs.generated
- add fuzz testing to math.vectors.simd
- add alien type support for integer SIMD vectors
- SIMD: parsing word generates a SIMD type, instead of pre-generating them all in math.vectors.simd
- Replace hand-written specialized-arrays.* subvocabularies with new system; instead of USE:ing specialized-arrays.T, do SPECIALIZED-ARRAY: T
- Ditto for specialized-vectors; use SPECIALIZED-VECTOR:
- io.mmap.functor: removed entirely, use <mapped-array> instead
- struct-arrays and struct-vectors have been removed because specialized arrays and vectors subsume them entirely
