Hello xWorld!

A short summary of the release:

• Fixed compatibility with rustc v1.71.0.
• Allocator system:
• Contracts can now choose their own allocator. This works in multi-contract contexts.
• New allocators: `fail` (default), `static64k`, `leaking`.
• Removed dependency to `wee_alloc`, but using it is still possible if the contract references it directly.
• Contract call stack size is now configurable in `multicontract.toml`.
• The 'panic with message' system now relies on managed buffers instead of on an allocator.
• Fixed BigUint bitwise operations in the debugger.
• When building contracts, an additional `.mxsc.json` file is created, which packs both the contract binary, the ABI, and some additional metadata.
• Refactor: reorganized the meta crate.
• Deprecated some legacy methods in the API wrappers.
