Check the validity of addresses in the SC statements #616

[apoorv-2204]

Description

• We have to raise an error, whenever there is malformed address given to any function of smart contract.
• The SC expects hex as binary, if binary not given it must be a string address.
• In elixir true binary is represented by <<>> while string encoded binary with "data"

Algo

• check if binary is true binary or string encoded binary
• check if its a valid hexadecimal number
• then convert to true binary
• check whether true binary is valid ae protocol address
