Set up Buf Generate

[haveanicedavid]

In regen-js, set up the buf generate with ts-proto + buf schema registry https://buf.build/regen/regen-ledger/ (we should also make sure we add all current proto files there, see https://github.com/regen-network/regen-ledger/tree/master/proto/regen)

There's an existing buf plugin for ts-proto stephenh/ts-proto#573 but since we're actually using a fork of ts-proto https://github.com/regen-network/ts-proto https://www.npmjs.com/package/@regen-network/ts-proto, we need to create our own plugin

Something to tackle pretty soon. Indeed in the protocgen.sh script, we use buf protoc, which has been removed as part of https://github.com/bufbuild/buf/releases/tag/v1.0.0 (see changelog there) so for the code generation to work, you'll need to use a version of buf prior to v1.0.0 for now, until we set up buf generate with buf yaml files. Please ping @AmauryM or @aaronc if you need any support on that when I'm on maternity leave.
