concordium-std 10.0.0

Summary

This release removes the (optional) dependency on the wee_alloc crate, which is no longer maintained.
To replace it, a new bump allocator is provided for use-cases where the contract logic is simple and a complex allocator is needless overhead.

Changes

• Remove the feature wee_alloc and replace it with bump_alloc, which enables a small and simple global allocator that can only be used in Wasm.
