I've updated the main branch (ctv) to match ctv-v2, and pushed branches
ctv-v1 which points at the prior versions.

Thanks to Dmitry Petukhov for helping me fix several typos and errors.

I also wanted to share some some "non-technical" tax analysis covering the
use of OP_CTV for batched payments. See here:
https://utxos.org/analysis/taxes/

As an aside, the site https://utxos.org/ generally is a repository of
information & material on OP_CTV, it's design, applications, and analysis.
If you're interested in contributing any content please let me know!

Best,

Jeremy
