Allow admin to disable Time Based One-Time Password on user accounts

[mdbitz]

In the plugin you can programmatically disable providers using the filter two_factor_providers https://github.com/georgestephanis/two-factor/blob/fced6f579161631791c525976a1dbb6211bef35c/class.two-factor-core.php#L85

I'd like to request the ability for Site Admins to disable providers per user. For example the ability to disable the "Time Based One-Time Password" for specific user accounts.
