Allow users to not add schema files when deploying programs.

Currently the CLI requires that users add the path to their auxilary and config schemas. This isn't strictly necessary, as programs can be deployed without them. There's a similar issue over in the the Entropy Core repo to remove the need for these files.

@johnnymatthews we're still nailing down the specification around schema. I think you're right this is gonna need to change, but will hold till we have more coherence before executing:

entropyxyz/sdk#418

Gotcha.

I tried supplying the CLI with a couple of empty .json files, but it didn't like that:

Deployment failed: SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at file:///home/johnny/Code/entropy/cli/dist/cli.js:11428:71
    at async EntropyProgram.deploy (file:///home/johnny/Code/entropy/cli/dist/cli.js:11535:33)
    at async deployProgramTUI (file:///home/johnny/Code/entropy/cli/dist/cli.js:11862:21)

    at async main (file:///home/johnny/Code/entropy/cli/dist/cli.js:12001:9)

Understandable since I think the CLI uses those files to display info back to the user.

Turns out you can use a couple of empty json blocks:

echo "{}" > auxiliary_data.json && echo "{}" > configuration.json

You can then use these in the CLI to deploy a program.
