Currently, the "unstable" feature no longer compiles on recent nightly
Rust toolchains, because it enables the const_generics feature flag.
Since const generics have stabilized, this feature flag is no longer
necessary, and results in a compilation error on recent toolchains.

This commit removes #[feature(const_generics)] from the crate. Now,
the "unstable" feature builds on recent nightly compilers. Additionally,
we can remove the "unstable" feature flag from the impls for converting
volatile arrays to slices, as that impl no longer requires an unstable
feature.

In order to make the tests pass on stable Rust after removing the
unstable feature flag from the impls for arrays, I had to modify the
examples so that they no longer use other unstable methods, such as
copy_from_slice. I think the new examples still get the point across,
although they're maybe not quite as nice...

Fixes #24
