feat(`cast`): add support for "cast decode-event" with indexed parameters

[drortirosh]

Component

Cast

Describe the feature you would like

I want to do

cast decode-event --sig "MyEvent(indexed bytes32 id, indexed address user, string name)"

but there is no way I can pass in the topics: the command only accepts the "data", which contains only the non-indexed parameters of the event.

(and as a side-issue, what I really want is also add "--sig" parameter to "cast logs")

Additional context

No response
