spndev_pending() not defined

[tksuoran]

I would like to use spndev_pending() but it does not seem to be defined.

Yes. The library is sill a work in progress in some respects.

One missing feature is an asynchronous interface. spndev_pending was an early idea on how to implement that, which I dropped.

In my local copy I am currently working on making the library and the test program compile (with Emscripten) and work in a web browser that supports the WebHID API. This port will certainly need to have an asynchronous interface. The reason I am doing it is because eventually I want the web version of SolveSpace to support 6DOF devices.
