This function transforms Lorentz values into script_expr.
script_expr is used in RPC as an argument in entrypoint
designed for getting value by key from the big_map in Babylon.
In order to convert value to the script_expr we have to pack it,
take blake2b hash and add specific expr prefix. Take a look at

expressionToScriptExpr :: Expression -> ByteString Source #
Similar to valueToScriptExpr, but for values encoded as Expressions.
This is only used in tests.
