IPFS library helpers are wrappers

This submodule contains wrapper implementations of IPFS-stack interfaces to introduce blocking-functionality as provided by NOpfs.

This submodule has its own go.mod and go.sum files and depend on the version of Boxo that we are building it for.

This submodule is tagged in the form ipfs/v<BOXO_VERSION>.<RELEASE_NUMBER> where the Boxo version corresponds to the Boxo release that the code targets and the release suffix to the release number for that version (in case of multiple).
