Add support for password protected documents

[lengoyvaerts]

This is a feature request as a result of this Elastic Discuss thread, which mentions #229

When trying to send a password protected document to the FSCrawler REST API, I'm getting the following exception:

Would it be possible to support a feature to allow password protected documents to be crawled? When using the crawler to crawl a directory, it could be something like a .password file as suggested in the Discuss thread. For the REST API, it could be an extra parameter in the request, e.g: -F "password=my-password" (could also be Base64 encoded maybe)

I would think Tika supports this, given the documentation for the PasswordProvider class
