Support multiple input sources

[endersonmaia]

To provide inputs comming from espresso, an --enable-espresso cli argument is being developed.

With --enable-espresso cli will disable the evm-inputreader and start a cartesi-espresso-reader together with a espresso-dev-node so the developer can work with inputs comming from espresso.

That being said, imagining a future where cartesi support multiple inputs sources, we'd get into a place where we could have a lot of --enable-<input-source>

Proposal

Add a --input-source = [ evm * | espresso | avail | ... ] (* default).

According to the input source defined, the infrastructure needed to use that input source should be started, like an espresso-dev-node and espresso-reader for --input-source=espresso, for ex..

This may also impact how the cartesi send command will work with the new input sources.

I think a better term, is case of espresso, is sequencer, instead of input-source.

You would do cartesi rollups start --sequencer espresso
