This is a PoC that aims to support multiformats/multiaddr#174 while not breaking existing Kubo users. See TODO in daemon.go – likely we want to move this to https://github.com/multiformats/go-multiaddr

IF It does not live in https://github.com/multiformats/go-multiaddr then multiformats/multiaddr#174 is effectively a dead spec IMO, because nobody will use percent-encoded version.

Why
/unixmultiformats/multiaddr#174is breaking spec change that is incompatible with existing feature in Kubo, where users were able to provide old notation of
/unixmultiaddrs in both Addresses.API and Addresses.Gateway.How
This is a PoC that aims to support
multiformats/multiaddr#174 while not breaking existing Kubo users.
