Allow to auto press enter on PIN length

[felipecrs]

Maybe a new option like:

--auto-enter-on-pin=<pin length>

So that I could use:

.\AuthenticatorChooser.exe --auto-enter-on-pin=6

And once 6 characters are entered in the PIN prompt, AuthenticatorChooser would automatically press Enter.

I am aware that it will increase the likelihood of doing too many wrong attempts and resetting my key, but this is perfectly okay for me and may be for others too.

But if that's really worrying, then maybe auto press should only happen once per dialog.

What do you think?

That's an interesting idea. I was always vaguely annoyed by this behavior, especially since TPM PINs do auto-submit but security key PINs don't. I'll see if I can get this working.
