Dash: Support spending DIP2 special transaction inputs (#351)
This implements support for spending of TX outputs which are part of a [DIP2](https://github.com/dashpay/dips/blob/master/dip-0002.md) special transaction, especially [DIP4 coinbases](https://github.com/dashpay/dips/blob/master/dip-0004.md#coinbase-special-transaction). This is for Dash only and thus required the addition of `is_dash` in `tx_api.py`. Support on the firmware side is not required for this to work as it reuses the logic from Zcash's `extra_data` and `extra_data_len` fields.
