Adds a new API call to fetch the underlying native hidapi version.

HidServices.getNativeVersion();
// 0.11.0

Note:

• This does NOT include the -dev suffix which is present in the native hidapi version information because hidapi does not expose this information.
• To avoid a NullPointerException, it will call HidApi.init() if needed. If this is undesired, please let me know.
