readme: renumber iteration alternatives. plan to keep this numbering.

readme: add some comments on implementation and alt iterator approaches

all: rename repo

readme: include some benchmark results

all: merge incremental growth, fuzzing call sequences via fzgen.Chain, self-validating map, cleaner benchmarks, more tests

map: possibly help with bounds check elim, additional benchmarks including for MatchBytes asm

perf: adding some stats, hid len ok checks behind debug const

map: put fmt behind debug const

map: passing tests, including force fill; might be passing benchmarks, but slow with fmt

map: intial working version, passes tests, has println, does not yet continue probing groups, so fails benchmarks

match: remove older .s and stub file, minor comment adjustment

mask: somewhat clean up avo code, reorder, add comments

match: initial tests, passing

working MatchBytes asm, in theory handles alignment
