Disposing UsbEventWatcher on Linux throws a null reference exception. about usb.events

Thank you, I will look into this as soon as I have time, hopefully in a few days.

Regarding the disposal of any Linux/Mac specific objects

https://github.com/Jinjinov/Usb.Events/blob/master/Usb.Events/UsbEventWatcher.Linux.c
https://github.com/Jinjinov/Usb.Events/blob/master/Usb.Events/UsbEventWatcher.Mac.c

The code for Linux and Mac is pure C, because it is not possible to do this in C#

https://github.com/Jinjinov/Usb.Events/blob/master/Usb.Events/Usb.Events.csproj#L34

as you can see here, the project file compiles the C code to .so on Linux and to .dylib on Mac

As I am not a C programmer, I wrote the C code with lots and lots of Stackoverflow help - I would say that there is no need to dispose of any C objects, but I am not 100% certain.

I made a simple fix, where the objects are null checked before disposing.

I have not been able to test in for Mac, but the updated version of the test application should be easy to use.
