Adds sign to event in the `round.new`.
Hash doesn't include other signs so event hash doesn't change upon adding signature.
`Command syntax:`
```actionscript
dag event sign
-net <net_name>
-chain <chain_name>
-event <event_hash>
-cert <priv_cert_name>
```
`Options:`
```actionscript
-net - name of the Cellframe network. The list of networks can be found in the <Config_dir> \ etc \ network folder folder or received by the Cellframe-Node-Cli Net List command
-chain - the name of Chain. The list of chain can be found in the directory <Config_dir> \ etc \ network \ <network_name> or get the Cellframe-Node-App Net List Chains command
-event - hash of the event
-cert - name of the private root certificate
```
### CLI Example
