Stylus eraser support

[dstillman]

A bunch of requests for this in the forums for various styli. Not sure if there's a general way to support all in the same way.

the stylii mentioned in the forum are made by different companies, but are all made for Wacon screens (samsung tablets and onyx boox eink devices) so this SDK should be helpful https://developer-docs.wacom.com/docs/sdk-for-signature/guides/android/

Onyx, the maker of increasingly popular "Boox" eInk and Color eInk android devices also offers an SDK to integrate its (very good) digital pen software into other android apps, see https://github.com/onyx-intl/OnyxAndroidDemo/blob/master/doc/Onyx-Base-SDK.md and this sample project https://github.com/onyx-intl/OnyxAndroidDemo .
