Encodes and Decodes OP_RETURN data used to trigger custom Swapbot actions.
Here is an example of how to create Swapbot OP_RETURN data to specify a custom destination for a swap:
$new_destination_address = '1JztLWos5K7LsqW5E78EASgiVBaCe6f7cD';
$encoder = new Tokenly\SwapbotOpReturn\Encoder();
$hex_string = $encoder->buildDestinationInstruction($new_destination_address);
echo $hex_string.PHP_EOL;
