The alloc data structures are useful in no_std environments and enabled by #![feature(alloc)] in the crate root.

Shouldn't have been commited anyway.

Also replace std::sync::Mutex with spin::Mutex from crates.io for no_std compatibility.
We still should search for a better alternative.

The [profile.release] attributes were managed by the workspace before.

Basically the same as in substrate-contracts-adder by pepyakin.

The problem with std::collections::HashMap is that there is no core::collections::HashMap or similar replacement for our no_std environment.
Also hashbrown seems to have superior performance.

This will help writing tests with general setup and tear-down mechanics.
Used to initialize env_logger for every unit test.

This also adds an alternative formatting for Key instances.

No longer needed due to the latest byte_util refactorings surrounding bytes_{add,sub}_bytes.

Also core::ops::{Add, AddAssign, Sub, SubAssign} impl for Key now log a warning if there is an overflow.
Add more tests.

They now use a common underlying implementation.
This fixes correctness bugs with bytes_sub_bytes.

This is going to be used by future core::ops::{Add,Sub} impls of Key.
