feat: upgrade to the new multiformats (#3556)

- Replaces the old [interface-ipld-format](https://github.com/ipld/interface-ipld-format) stack with the new [multiformats](https://github.com/multiformats/js-multiformats) stack. - The Block API takes/returns `Uint8Array`s instead of [ipld-block](https://github.com/ipld/js-ipld-block) objects BREAKING CHANGE: ipld-formats no longer supported, use multiformat BlockCodecs instead Co-authored-by: Rod Vagg <rod@vagg.org> Co-authored-by: achingbrain <alex@achingbrain.net>
