feat(cast abi-encode-event): add support for event encoding to get topics and data

[Jds-23]

Component

Cast

Describe the feature you would like

Currently, there's no way to encode event to get topics. It would be useful to have something like

cast abi-encode "event Approved(address,uint256)" 0x... 1
output:

It can either be cast abi-encode or cast pretty-event.

i would love to raise a PR myself, just let me know if you guys agree this would be useful and is not a redundant feature.
