I would like to be able to create a transaction that include delegation certificate for a 3rd party (the stake key owner) that will sign the tx lately.
To do so the address package should be improved to facilitate the management of stake addresses (aka reward addresses), and allow the tx builder to know that the transaction will be signed by a well known number of witnesses in advance, to be able to calculate fees correctly.

Add support for partially signed tx, closes echovl#38

* allow to set additional witnesses for partially signed tx preparation
* change calculateMinFee to consider additional witnesses that will
  increase the tx length. It is still not clear how to precisely
  calculate the bytes for witnesses, in this implementation
  for each additional witnesses there will be an additional 100 bytes,
  (32 public key, 64 signature, 4 index/key in cbor). Those are not
  actually enough so we are considering 1 additional byte
  for each additional witness after the first.
