Implement encode/decode 1inch extension (#75)
* Add encode/decode 1inch extension * Fix lint * Add interaction * Implement interaction * Implement encode/decode auction details * Implement encode/decode settlement post interaction data * Add fusion extension decode * Convert auction details to use primitive types * Convert settlement post interaction data to use primitive types * Replace extension fields by byte arrays * Convert string to []byte * Sink some packages * Shorten function encode * Make lint happy * Remove trim0x function * Remove ZX global constant * Use math.PaddedBigBytes instead * Check data length before get it from bytes * Add next function at decode package * Implement bytes iterator * Remove completely zx * Remove unused assert in test * Add check less than 0 when create auction details * Remove big package in bytes iterator * Add assert for some tests * Return offset is a common.Hash
