Now there's an API(https://mainnet-api.explorer.nervos.org/api/v2/statistics/contract_resource_distributed) to get the contract resource distribution

It covers 80 scripts.

The user want to focus on a set of scripts, so they wonder if a filter of code hashes can be supported for the API, e.g.

https://mainnet-api.explorer.nervos.org/api/v2/statistics/contract_resource_distributed?code_hashes=code_hash_1,code_hash_2
