Client support for grpc-web-text

[siebert]

I want to use the sonora client to connect to a server which only supports gprc-web-text, but currently only gprc-web+proto is supported. Is it planned to implement this variant in the sonora client as well?

gprc-web-text is the variant with additional base64 encoding of the bodies right? I think this would be easy enough to support. I don't have plans to do it but would happily help get a PR merged :)
