Description: `Aims to prevent a transaction from being added to the blockchain by dispatching a more
prioritized conflicting transaction to the specified RPC node. The input for this command should
be the transaction hash. If another account is not specified, the conflicting transaction is
automatically generated and signed by the default account in the wallet. If the target transaction
is in the memory pool of the provided RPC node, the NetworkFee value of the conflicting transaction
is set to the target transaction's NetworkFee value plus one (if it's sufficient for the
conflicting transaction itself). If the target transaction is not in the memory pool, standard
NetworkFee calculations are performed based on the calculatenetworkfee RPC request. If the --gas
flag is included, the specified value is added to the resulting conflicting transaction network fee
in both scenarios.
