Thanks for the PR!

Some notes:

1. Let's have separate options for reading from a file vs supplying the data on the command line.
2. Please document the new options in the README file
3. Please fix the eslint issues to make the build past

Hi @urish

Thanks for the reply. I will split the options and fix the linting issues.

As for readme, I though as you have the note

For more information, run:

	node_modules/.bin/firebase-server -h

in the readme and other options are also not documented, the cli should document itself. Let me know if updating the readme is still necessary

One question to @urish :

Would you prefer the command to fail if a given file or JSON is invalid, or just start anyway with {} as data?

[urish]

It should fail in this case. thx!

[mediavrog]

@urish Made the changes. If you're good with it, please squash-merge. Cheers

[urish]

Looks good - one last thing, can you please document the new options in the README file?
