This package has never compiled, and nothing here ever asked it to - #1

build.zig declared pub fn test, and test is a keyword. It also assigned
b.standardTargetOptions without calling it, passed two arguments to
installArtifact, and read b.step as a field. None of that is a version
difference: it is a sketch shaped like a build script, and nothing here ever ran
it because no workflow built anything.

The manifest was equally unusable -- a string where 0.15 requires an enum
literal, and no fingerprint -- so this package could not be depended on by
anything either.

src/root.zig now has a test target and refAllDeclsRecursive. It is the surface a
consumer gets and it was the one surface never compiled.

src/root.zig re-exported everything as 'pub use module.{ A, B as C };'. Zig has
no use statement and no as aliasing, so this file -- the surface every consumer
imports -- has never been valid Zig, and this package has therefore never been
usable by anybody.

Five such blocks, now sixty-seven pub const declarations with the aliases
preserved exactly as they were spelled.

Nothing reported this in the lifetime of the repository, for the same reason
nothing reported the build script that declared 'pub fn test': there was no
workflow that built anything, so the question was never asked.

Same shape as gHashTag/zig-golden-float#95, and the same shape as root.zig: a
file inside src/ writing @import("src/simd_config.zig") asks for
src/src/simd_config.zig. The target is one level above where the import looked.

The Rust-style blocks listed VEC_F32_SIZE, DEFAULT_SYNC_INTERVAL,
DEFAULT_QUANTIZE_THRESHOLD, TRIT_NEG, TRIT_ZERO and TRIT_POS. None of those is
exported by the module it was taken from. Nothing could ever have used them,
because the file naming them has never compiled -- so they are dropped rather
than invented.

simd_config used std.io.getStdOut, removed in 0.15. A File writer borrows a
buffer the caller owns, so the buffer lives at the call site now.
