HID: bpf: add support for Huion Kamvas 13 (Gen 3) (model GS1333)
This assumes that the tablet has been switched into vendor mode (by
using huion-switcher[1], for example) and is sending events using
Huion's proprietary data format.
This has been tested using the PW600L pen, which does not have an
eraser. There is no expectation that a pen with an eraser will work at
this time.

/*
35
+
* This tablet can send reports using one of two different data formats,
36
+
* depending on what "mode" the tablet is in.
37
+
*
38
+
* By default, the tablet will send reports that can be decoded using its
39
+
* included HID descriptors (descriptors 1 and 2, shown below).
40
+
* This mode will be called "firmware mode" throughout this file.
41
+
*
42
+
* The HID descriptor that describes pen events in firmware mode (descriptor 1)
43
+
* has multiple bugs:
44
+
* * "Secondary Tip Switch" instead of "Secondary Barrel Switch"
45
+
* * "Invert" instead of (or potentially shared with) third barrel button
46
+
* * Specified tablet area of 2048 in³ instead of 293.8 x 165.2mm
47
+
* * Specified tilt range of -90 to +90 instead of -60 to +60
48
+
*
49
+
* While these can be easily patched up by editing the descriptor, a larger
50
+
* problem with the firmware mode exists: it is impossible to tell which of the
51
+
* two wheels are being rotated (or having their central button pressed).
52
+
*
53
+
*
54
+
* By using a tool such as huion-switcher (https://github.com/whot/huion-switcher),
55
+
* the tablet can be made to send reports using a proprietary format that is not
56
+
* adequately described by its relevant descriptor (descriptor 0, shown below).
57
+
* This mode will be called "vendor mode" throughout this file.
58
+
*
59
+
* The reports sent while in vendor mode allow for proper decoding of the wheels.
60
+
*
61
+
* For simplicity and maximum functionality, this BPF focuses strictly on
62
+
* enabling one to make use of the vendor mode.
