Bump version to 0.27.0

[RCasatta]

The minor version increment is due to the breaking changes in #601 and #521

[Kixunil]

I just noticed this TODO

Maybe it should be addressed?

utACK

@Kixunil good catch. I think this can wait for the next major release (Taproot support) which shouldn't be too much longer. I'd like to get this one out ASAP because it's blocking some embedded users.

utACk ef69f24 . Tested that this does not break anything(unexpected) for rust-miniscript downstream.

[sanket1729]

Before we tag a release, I think we should check that this does not break anything expected for a few major projects(BDK, rust-lightning). This is to avoid issues like #608
This is a major version change, so it's not a big deal. But still good to check

I verified that BDK builds and has no test failures with current master (without version bump commit). To build with 0.27 at least our bitcoincore-rpc crate would need a version bump too afaik.

I used the following diff with ../rust-bitcoin being at df4d70a and BDK at v0.9.0 (commit bitcoindevkit/bdk@4e813e8).

[Kixunil]

Loptos also works. :)

Sounds like we're good to go :)
