Update package to version 3.0.0:
- Simplify getGasParams function by including additional L1 fee in gasLimit - Make calculateRefund functions non-async by providing gas price (its ok, because refund needs to be calculated only on user side, where gas price is known) - Allow passing to calculateWithdrawalFeeViaRelayer function predefined gas price and gas limit to not refetch/recalculate those values - Pass arguments as objects to functions with many optional parameters
