To drive my point home, here's a PR converting the `writer` part of your
code to a protobuf-compatible version. It took me less than an hour to
write, the bigger part of which was spent orienting myself in unfamiliar
code. I assume I could do `reader` in less than that, if your
deserialization code was complete.

This code produces PSBTs that my "bip174 playground" can correctly parse.
