Embed Notice

`string.pack`/`string.unpack`/`string.packsize` interprets a mini-lang which (ignoring whitespace) precedes chars indicating a type with "<"/"="/">" as endianness & "!"-prefixed alignment.
Usually the type-char indicates an integer's byte-width & whether its signed, though "d" & "f" represents floats whilst "c", "z", & "s" copies however many bytes out as strings. "x" & prefix-"X" ignores the bytes as padding.

Interpret using Assembly, ideally using our maybe-ops to avoid branching!
