stop using the "[id: string]: any" pattern to suppress type errors

[jellegerbrandy]

but instead follow @dOrgJelli 's suggestion: "If the only reason it exists is to suppress the typescript compiler error on line #33, then there is another way. Adding "suppressImplicitAnyIndexErrors": true to your tsconfig.json will get rid of the error when you use the index operator on the object."

We did, but this makes implement #227 much more cumbersome, because we have to copy all the query options that graph-node provides into the search types...

[jellegerbrandy]

Reverting this change, as we need the flexibility in alchemy and we do not want to be bothered by copuing explicitly ALL query options of the subgraph.
