arrays and wrappers

Full Changelog: v0.6.0...v0.7.0

• support [u8; N] for 0..=32
• rename exposed error type to avoid collisions
• add support for deriving tuple structs of one member to facilitate the "new type" pattern

one error to rule them all

Full Changelog: v0.5.0...v0.6.0

Expose one "wrapping" Error type to simplify the error story for consumers of this library.

others can merkle too

Full Changelog: v0.4.0...v0.5.0

Expose tools for others to write hash_tree_root implementations.

reality comes at you fast

Full Changelog: v0.3.0...v0.4.0

This release includes a number of features to support the use of this library in a realistic setting, namely ethereum_consensus.

three's a crowd

Minor fixes realized while using the crates in this repo in https://github.com/ralexstokes/ethereum_consensus geared towards usability and Clippy lints.

as the roots undo

Adds a SimpleSerialize implementation for the Root type defined in this crate.

Without this implementation, ssz_rs users cannot define types that use Root as "summaries" of their committed data. Due to rules of the Rust trait system, this implementation needs to live in this crate and cannot be defined externally.
