Add ethportal.net tooling about ethereum.nix

[cryptix]

I'm fairly familiar with nix but no so much with rust. While I was able to build glados in an ad-hoc nix-shell -p rustc cargo libiconv darwin.apple_sdk.frameworks.SystemConfiguration., this failed for trin because it needs rustc 1.79.0 and my nixpkgs still only has 1.78.0.

I therefore tried to copy the reth package description and adopt it to build trin. However I'm running into this odd error and was hoping someone here more familiar with the rust toolset has any insight:

error:
       … while calling the 'derivationStrict' builtin

         at /builtin/derivation.nix:9:12: (source not available)

       error: No hash was found while vendoring the git dependency alloy-consensus-0.1.0. You can add
       a hash through the `outputHashes` argument of `importCargoLock`:

       outputHashes = {
         "alloy-consensus-0.1.0" = "<hash>";
       };

       If you use `buildRustPackage`, you can add this attribute to the `cargoLock`
       attribute set.

I do have the cargoLock.outputHashes attributes, even with that dependency, as reth also needs it. So i'm a bit confused why it doesn't take / see it. Maybe this could be a workspace issue? trin and glados both have multiple sub-projects but it seems like glados is building fine... I will polish up my WIP branch in a bit.

My WIP is at https://github.com/cryptix/ethereum.nix/tree/add-ethportal I based it on #523 for a more recent rustc version.

All the glados tooling is there but trin still fails to compile with the above issue.
