Package hexutil implements hex encoding with 0x prefix.
This encoding is used by the Klaytn RPC API to transport binary data in JSON payloads.
Encoding Rules
All hex data must have prefix "0x".
For byte slices, the hex data must be of even length. An empty byte slice
encodes as "0x".
Integers are encoded using the least amount of digits (no leading zero digits). Their
encoding may be of uneven length. The number zero encodes as "0x0".
Source Files
`hexutil.go` has functions to provide hex encoding and decoding.
`json.go` implements functions of encoding/TextMarshaler, json/Marshaler and json/Unmarshaler.
