Enables std of memchr and no-std-compat

memchr:

The 'std' feature permits the memchr crate to use the standard library. This permits this crate to use runtime CPU feature detection to automatically accelerate searching via vector instructions. Without the standard library,
this automatic detection is not possible.

StringRing has 2 features without comments.
