Crash in HCaptcha 4.0.3

[daldegam]

Some reports of crashes from my users when the hcaptcha should be displayed.

After some analysis, I managed to find a device that I can reproduce the crash.

To reproduce the crash, simply display the hcaptcha to the user, and the crash happens instantly.

Device: Samsung J5 (SM-J500M)
Android 6.0.1

This crash does not occur in version 4.0.2.
Which leads me to believe that it was introduced when this fix was applied:
#167

Thanks

Yep FasterXML/jackson-databind#3657 is require Android 26, so reverting dependency back to 2.13.x in #171
