fix: update all deps to versions that return uint8arrays (#286)

Removes use of node Buffer in favour of Uint8Arrays and updates
all dependencies to versions that do the same.

BREAKING CHANGES:

- CIDs returned from `put*` methods have breaking API changes
  See see multiformats/js-cid#117 for changes
