Closes #532
Adds type-safe support for relaying packages.
Currently, the only supported package type is 1P1C, so this leveraged when sharing the transactions. First the child transaction is shared by
Wtxid, which includes inputs that will be unknown to the receiver. The parent is never shared explicitly, instead we expect the receiver should request the inputs by their previous outpoint. The outpoint uses the legacyTxid, so parent transaction data is stored in a second map, indexed onTxid. Packages are confirmed only once the parent has been shared. In the case of a single transaction, the flow of data does not change.
