Upgrade zmq2 0.5.0 -> zmq 0.10.0

[yanganto]

zmq2(0.5.0) and zmq-sys2(0.3.0) are in legacy and have not been in maintained for a while, and it seems zmq is the one that should be used after Sep 2, 2022.

Thank you, but this package is not anymore used by our software stack. Right now we do not have a nodes which are maintained, and future versions of them should use rust-netservices instead of this repo.

The lnp-node is eventually dependent on this.

Currently, lnp-node is the only lightning node that supports RGB protocol, I think this is important so I am updating this.

If we can bounce the version to 0.9.1, I can update the rest crates (lnp-core, microservices) based on internet2 and also needed by lnp-node. 🙏

Nope. First, it works with very old RGB version, i.e. can't be used with modern RGB assets. Second, there is a LDK-based node from Bitfinex, which is the main LN node to be used with RGB.

There is a plan to eventually update LNP node, but it will take nearly a complete node re-write, so we will be also able switch to rust-netservices.
