During the changeset calculation after the `openchannel2_sign` hook. So this commit patch the problem with the following change: - Addressed an issue where `psbt_get_changeset` was modifying the original PSBT unnecessarily. - This modification led to problems with a different hsmd, as referenced in [Issue #6672](https://github.com/ElementsProject/lightning/issues/6672). - Noted a potential optimization where only a subpart of the PSBT needs to be cloned, as the mutation is specific to inputs.

These are standard bitcoin manipulation routines which should be provided by any normal bitcoin library in whatever language you choose. The ones here are standalone ones taken from bitcoin core and some I wrote, many taken from bitcoin-iterate and pasted in here.
