Descriptor script fragment

Miniscript is great, but:

1. Can’t represent many wallet types inside descriptor (lightning wallet, multisigs re-using keys in different branches)
2. Do not yet supports tapscript
3. Still not stable, i.e. not durable enough for long storage of wallet descriptor backups

As of today, there is no standard way to write a descriptor covering all forms of UTXOs which may be present in bitcoin transactions. This standards aims to bridge that gap. It also defines a canonical form of a wallet descriptor, which is unique for each wallet and allows to commit to the wallet structure in a non-ambigous way, which may be important for wallet comparison, identification, especially in multi-party protocols.

On the 12th of April, 2022 I was "temporally suspended" by Andrew Poelstra from being a maintainer of rust-bitcoin repository. I was notified about this action by a letter from him without any prior discussion. The cause of the decision was my public expression of the statement that cases of plagiarism must not be tolerated and must be acted upon (thread starting from https://twitter.com/dr_orlovsky/status/1513555717218873355?s=21).

Andrew referenced to the fact that while rust-bitcoin is an anti-CoC community, he still considered my words as those which can't be acceptable for a maintainer of rust-bitcoin, since they may be read as a threat of physical violence. We had a mailing after, where I clarified that there were no threats of physical violence. I was surprised that ethic compatibility was a part of requirements for being rust-bitcoin maintainer, which was not what I expected from "anti-CoC" policy of the repo. Andrew agreed that this "anti-CoC" policy and requirements for maintainer conduct are in co
