Description

Extracted from #8180 (comment):

a transcode function so that you don't have to do ipfs multibase decode | ipfs multibase encode -b=base16, but can instead do ipfs multibase transcode -b=base16. Not having this makes life pretty painful for environments that don't tolerate binary outputs well (e.g. PowerShell, but I suspect there are others)

It sounds useful even if we address #8335 at some point.
