OKBoard experimental

PawelSpoon (https://github.com/PawelSpoon/OkBoard) made some tiny changes to allow OKBoard on devices like the Xperia XA2 Plus. It offers an exellent user experience on that device in my opinion, but as the creator of OKBoard (eber42) states in https://openrepos.net/content/eber42/okboard, he won't support devices he can't test himself.

So this "experimental" version is just a rebuild of the offical OKBoard, but it allows some unsupported dimensions of keyboards. So please, no feature requests or bug reports, as there is no support for this version from the author.

Do NOT install this version if your device is already supported, but just use the regular version in that case. This version will conflict the offical version anyway.

Devices with good user experience:

• Xperia XA2 Plus
• Jolla Tablet
• ?

The version uploaded is the latest from eber42, working on SFOS 4.5.

If other, similar devices are reported to work or not (that I can't test) I could add them to the current list of devices.
