File hardhat-changes contains all changes made to hardhat repository made locally to overcome invalid response foreth_getBlockByHash and eth_getTransactionByHash

Godwoken RPC call eth_getBlockByHash returns some fields with value equal to zero like for this call for block 0x9207b685f981f6bdd1a191de60db31557bafc4774cb2093b395a6c4407b0e6f3:

This is problem for hardhat fork feature beacous we need to be able to calculated block hash from these parameters but since some of them are equal to zero the calculated hash is invalid. Godwoken RPC should return correct parameters that would get same hash for calculated and rpc hash in the getBlockByHashTest.js file.

Similar issue related to eth_getTransactionByHash but it's not clear which values in RPC call are incorrect. Test regarding calculated and received tx hash is avaible in getTxByHashTest.js.
