Add RapidCaptcha Support as a Captcha Solver

[DevWaveJourney]

Hello,

I'd like to suggest adding support for RapidCaptcha as a captcha solver.

RapidCaptcha is dedicated to solving: reCAPTCHA v2, reCAPTCHA v3, Invisible reCAPTCHA, Image Captchas

RapidCaptcha offers very affordable pricing and a simple API integration.

API Docs:

I'd be happy to help with testing if support is added.

Thanks!
