Improves website loading speed by lazy loading reCaptcha for Contact Form 7.

Description

Usually, reCaptcha scripts load immediately in Contect Form 7. Regardless of whether you use the async or defer strategy, reCaptcha script execution requires a significant amount of device resources, which is very noticeable on mobile devices.

The idea behind the plugin is simple: load and execute reCaptcha only when the user starts interacting with the contact form. This results in a significant increase in loading speed, but it can lead to worse spam detection (see FAQ).
