Android 64bit support

[chkatz]

By August 1, 2019, 64 bit support is required for android apps. Are there any plans for updating the vuforia sdk to the latest version with 64 bit support?

Hi @chkatz, I've not got any immediate concrete plans - the process of upgrading the SDK is quite onerous and it is my understanding the at the 'classic' license model that this plugin supports is no longer offered.

It's a shame but at the moment I'm not in a position to consistently support the library - any efforts on my part will be ad-hoc.

I'd be more than happy to accept a PR though if you, or anyone else was interested
