Support for sortedmulti_a

[dr-orlovsky]

The support is part of Bitcoin core, but absent here

Note that this would only be supported at the top level. Supporting it at the miniscript level is not possible and is currently not in spec. Same reason why miniscript only has multi and no sorted_multi

Is it possible to remove this issue from the 8.0.0 milestone so that the next release can go out sooner? Projects like bdk need #450 before we can update to rust-bitcoin 0.29.

I would also like #478 -- let's bump this to the next milestone so we can do a quick release. Ok by you @sanket1729 ?

Oh, actually I don't care (I'm working on elements-miniscript but it is just a fork off the git repo, it doesn't use crates.io versions). But I agree with the sentiment that we ought to have a current release that matches rust-bitcoin.

[sanket1729]

In future releases, we should automatically release a new version of rust-miniscript whenever there is a new version of rust-bitcoin. Other normal feature releases of rust-miniscript can go at their own pace.

I will prepare a new release ... but apparently we have 71 PRs since the last one so it may take me a while to make a changelog!

[sanket1729]

@apoelstra, I think I made some progress on changelog

[sanket1729]

Let me check my local branh

@apoelstra, there is already a changelog at 6f3c967

Adding top-level support for sortedmulti_a is certainly something we want to do. But something I don't have the time for now. Perhaps, a simple good first issue for someone who is looking for intermediate coding.
