[FR] - Implement treasury donations on the CLI

[CarlosLopezDeLara]

Internal/External
Internal if an IOHK staff member.

Area
Transactions, treasury donations.

Describe the feature you'd like
Update conway transaction build and build raw commands to support the new "donate to the treasury" feature.

A new flag --treasury-donation should be enough. This requires a change on the API

conway cddl:

transaction_body =
  { 0 : set<transaction_input>             ; inputs
  , 1 : [* transaction_output]
  , 2 : coin                               ; fee
  , ? 3 : uint                             ; time to live
  , ? 4 : certificates
  , ? 5 : withdrawals
  , ? 7 : auxiliary_data_hash
  , ? 8 : uint                             ; validity interval start
  , ? 9 : mint
  , ? 11 : script_data_hash
  , ? 13 : nonempty_set<transaction_input> ; collateral inputs
  , ? 14 : required_signers
  , ? 15 : network_id
  , ? 16 : transaction_output              ; collateral return
  , ? 17 : coin                            ; total collateral
  , ? 18 : nonempty_set<transaction_input> ; reference inputs
  , ? 19 : voting_procedures               ; New; Voting procedures
  , ? 20 : proposal_procedures             ; New; Proposal procedures
  , ? 21 : coin                            ; New; current treasury value
  , ? 22 : positive_coin                   ; New; donation
  }
