Subject: [PATCH] Introduce `ahash-compile-time-rng` feature.

Disables the default features of `ahash` and reintroduces them
through a new feature called `ahash-compile-time-rng`, which is
enabled by default.

The new feature makes it possible for depended crates to rely on
`hashbrown` with `ahash` as default hasher and to disable the
`compile-time-rng` at the same time.

This might be useful for any dependent crate targeting `no_std`,
which contains `rand` or `rand_core` somewhere inside the dependency
tree as a bug in cargo accidentally enables the underlying `getrandom`
feature if `compile-time-rng` is enabled [1].

... fixes #124
