Allow named parameters in event signatures

[PaulRBerg]

Idea

Is there any reason why event signatures cannot contain named parameters in a subgraph manifest?

Surely the graph-cli could strip out the names from the signatures when looking for the corresponding match in the ABI.

Other indexers like Envio require the event signatures to contain the names of the parameters, which makes code reusability between our subgraphs difficult.

Logs

I am getting this error when trying to run codegen with a subgraph manifest that contains named parameters:

✖ Failed to load subgraph from manifests/ethereum.yaml: Error in manifests/ethereum.yaml:
