[Feature] Ability to specify language through Directive

[dwfe]

Summary

I'm submitting a:

• [x] feature request

Description

Now we can specify the language in the module.

But in case the user can change the language via the interface, then I have no way to pass the language changes to the re-captcha component.

Could you expand Input Options with a Directive, that would allow you to pass the language to the re-captcha component.

Lib versions:

• ng-recaptcha: 4.0.0-beta.1
• Angular: 6.1.4
• Typescript: 2.7.2

Hello @dwfe ! Thx for reaching out.

There have been multiple attempts to do that in the past, both from myself as well as from contributors, and they had various downsides:

• relying on solely the public reCAPTCHA api resulted in unstable behavior after language has been changed
• relying on internal reCAPTCHA api was stable, but did not guarantee that the solution will always work - we don't have full control of internals and would be at the mercy of reCAPTCHA core team

I agree that it would have been a great feature.

There are no plans to get back to that for now, but I'll leave the issue open
