Add type support for ethers v5 queryFilter

[zemse]

event Transfer(address sender, address receiver, uint256 value);

const filter = contractInst.filters.Transfer(); // TransferFilter

const logs = await contractInst.queryFilter(filter) // Overloaded for each filter

logs[0].args // before `any`, but after this feature it should be `{sender: string, receiver: string, value: BigNumber}`

I'll give this a shot while doing my next project starting probably end of this month or next month.

Sounds like a good idea. You'll probably have to add a special EventFilter subtype for each event. Or make it a generic type based on the event param types, so then the new function would simply be like queryFilter<PT>(TypedEventFilter<PT>): Promise<Array<TypedEvent<PT>>>. Or another approach is it makes the resulting code easier to use 👍

@zemse Shouldn't this be closed?
