Dependency conflict when trying to use rgb-node in another project

[jharveyb]

rgb-node builds fine for me as its own crate, but when I try to include it in a separate project, I get this error upon cargo check or cargo build:

error: failed to select a version for secp256k1-sys.
... required by package secp256k1 v0.18.0
... which is depended on by bitcoin v0.24.0
... which is depended on by miniscript v2.0.0
... which is depended on by lnpbp v0.1.0-rc.2 (https://github.com/LNP-BP/rust-lnpbp?tag=v0.1.0-rc.2#96832d9b)
... which is depended on by rgb_node v0.1.0-rc.2 (https://github.com/LNP-BP/rgb-node?tag=v0.1.0-rc.2#a46423d6)
... which is depended on by $MY_PROJECT
versions that meet the requirements ^0.2.0 are: 0.2.0

the package secp256k1-sys links to the native library rustsecp256k1_v0_2_0, but it conflicts with a previous package which links to rustsecp256k1_v0_2_0 as well:
package secp256k1-sys v0.3.0
... which is depended on by secp256k1 v0.19.0
... which is depended on by bitcoin v0.25.0
... which is depended on by electrum-client v0.3.0-beta.1
... which is depended on by rgb_node v0.1.0-rc.2 (https://github.com/LNP-BP/rgb-node?tag=v0.1.0-rc.2#a46423d6)
... which is depended on by $MY_PROJECT

failed to select a version for secp256k1-sys which could resolve this conflict

This error is also present for the v0.1.0-rc.1 tag, but not v0.1.0-beta.4.

Sorry, I forgot to add the same section as in LNP/BP Core lib readme: https://github.com/LNP-BP/rust-lnpbp/#use-library-in-other-projects

So you need to add this to your project using either RGB Node or LNP/BP Core libraries.

This is temporary: with the release of upstream rust-bitcoin crates we will be able to do a release of our libs as well (hoping this will happen this week) and this fix would not be required anymore

Confirmed that this is fixed with the v0.1.0 release, can be used from crates.io as expected.
