* ibc v3 upgrade

* ibc no longer uses confio

* add proofs proto for ibc/v3

* wip add ethermint module

* update cosmos to 0.45.0

* add ethermint proto & bug fixes

* remove todo

* update docs

* fix a number of bugs

* minor comments update

* fix breaking tests

* Wrap bank keeper for EVM to convert decimals (#1154)

* Add bankkeeper wrapper for evm

* Remove agas from init-new-chain.sh, use ukava for evm_denom

* Fix sdk.Coins conversion, require min 1 coin amount

* Remove gas from init script

idk how this happened lol

* Remove debug logging stmt

* Restore original init ukava amounts

* Fix inplace coins conversion

* Use evmtypes.BankKeeper interface insteadof banktypes

* Add TestGetBalance

* Add doc comments, remove temp actualAmt vars

actualAmt vars replaced with inline calls to make it more clear that the
converted value is being used, as opposed to accidentally reusing the
raw EVM amt.

* Add TestSetBalance

* Add TestIdempotentConversion

* Panic if converted coin from EVM is 0

This happens if a value is less than 1ukava

* Deep copy coins instead of in place modification

* Update test coins amount

* Add panic tests for small EVM amounts

* Use evmtypes.BankKeeper as NewEVMBankKeeper param

* Tidy test setup

* ensure sdk config is set when creating new apps

* Respond EVM bank keeper GetBalance with SpendableCoins
