btcpayserver: 1.3.3 -> 1.3.6
electrs: 0.9.2 -> 0.9.3
lnd: 0.13.3-beta -> 0.14.1-beta
nbxplorer: 2.2.16 -> 2.2.18
electrs does not accept command line argument -vv anymore, so we have to use
--log-filter instead.
This change is fully backwards compatible.
We continue to use the standard non-flake evaluation mode in our
examples and internal tooling until the flakes design has stabilized.
'clightning-plugins = pkgs.recurseIntoAttrs' in pkgs/default.nix is
needed by flake-utils.lib.flattenTree in flake.nix.
It transforms the packages in `clightning-plugins` to top-level packages
named like `clightning-plugins/summary`. (The flake attr `packages`
must be a non-nested attrset of derivations.)
