Fix ABI encoding of Nitro state to match javascript implementation - rewrite ABI encoding to properly handle dynamic tuples - surround Nitro types with extra tuples to match javascript - test with examples of encoding extracted from javascript 2021-02-25 09:11:46 +01:00			`import pkg/stew/byteutils`

Fix ABI encoding of Ethereum Addresses They should be encoded as if they were UInt160, which means they should be left-padded with zeroes, instead of right-padded. 2021-02-23 10:23:42 +01:00
