Transaction chaining after another transaction or after certain block hash

[mgajda]

The problem that you wish to solve

If we have just received the block or transaction with a specific hash, and we want to make another transaction only if the previous has been confirmed.

Description

We would like to create or submit transaction after a fixed block number and hash, or after a fixed transaction id and block number.

In case of transactions, this is called transaction chaining and may greatly improve performance.
In case of blocks, this enables other blockchain players to react much quicker to certain blockchain events.

In both cases it would greatly improve performance, while allowing higher level of safety than submission of transaction without such dependency.

Implementation suggestions

This would require additional arguments to cardano-wallet CLI that would enable these.
