Due to the small capabilities of the blender api for hair particles, I was unable to implement a private particle system. But you can create bezier curves (having a volume to render) or a geometry mesh (which you can snap to the skeleton) and hair skeleton bones.
Using the addon on my Ubuntu machine having issue. When I click the button to build a new map gives some random errors and hair doesn’t shows up when creating new hair preset. Also couldn’t find any preset.
I tried many times to start making a new version of the addon over the past year, but often the process just fell apart.

Now a lot has changed and support can be permanently closed.
However, if you need more, I may have fixed the compatibility bug with 3.1
The update is already on github
