BCDetect appears to break with Google's reCAPTCHA

[0xdevalias]

A teammate passed on this issue to me today to raise with you guys.

It seems that BCDetect will break when trying to process a site using Google reCAPTCHA.

The following URL, run through BCDetect, will cause a bunch of issues:

• https://patrickhlauke.github.io/recaptcha/

Errors produced are similar to the following:
