It will be useful to export multiple index*.html files in a single run of npm run package, in order to host multiple presentations in the same package.

The idea is to consider multiple parameters passed to the npm run package command.

Current behaviour:

const htmlTarget = args.length > 0 ? args[0] : 'index.html';
// handle single file

Desired behaviour:

const htmlTargets = args.length > 0 ? args : ['index.html'];
// iterate through all the targets

So when users run, for example, npm run package index*.html it will consider every index*.html file in the root directory, not just the index.html file

I will try to work on a PR for this
