Token balances ethereum

[aalan3]

This should be considered a beta version of token balances so this is not yet exposed. The tables are split by native and erc20 tokens because doing everything together uses too much memory in Trino, these are considered intermediary tables and are unioned together in the main table balances_base.

Some notes:

• Gas fees and block rewards are not in transfers yet so they will not be counted here
• We have to cast to double before the sum() because there's no way of catching overflows that happen inside of a aggregation at the moment
• For other bigger chains we likely have to split up the tables to create even more intermediary tables

This is ready for reviews but native balances are not correct

are you good with my commits?

it timed out, as expected. we can still look to merge tomorrow, if you are good with the current state.

Yeah thank you! I was going to do transfers in a separate PR but might as well do it here. Tests are also a good idea.
