Smart contract standard codec

Lightweight binary serializer/deserializer, written especially for MultiversX smart contracts.

Designed to:

• produce minimal WASM bytecode
• be fast
• avoid data copy as much as possible

Largely inspired by the Parity SCALE codec, but a completely different format and implementation.

For more info about the serialization format, see the developer reference.

no-std

Being designed for MultiversX smart contracts, it needs to be able to run in a no-std environment.

It is also safe to run in a regular std environment.

The types provided by default all work without an allocator. To use an allocator, pass feature flag "alloc".
