Should we just update ethjs-query? What will be the difference by using the provider directly vs. using ethjs-query?

Explanation
Problem:
At the moment, we don't support accessList in transactions. This is a feature added by eip-2930, and in certain cases leads to gas used savings.
Solution:
At the very least, we should allow proxying eth_createAccessList calls to the connected network, and pass the transaction field
accessListto be passed in for signing. We also allowaccessListto be passed into estimate gas.Future considerations:
We can determine, for most cases, if providing an access list will amount to gas savings. There are however some cases where we wont know until after the transaction is added to a block, since the transaction and associated access list might be dependant on the state of a particular block, and become suboptimal in the next. We could explore ways of detecting these situations, but it would be pretty elaborate and so automatically creating accessLists was left out of the scope of this PR.
