Trouble loading ftdi d2xx lib under Windows7 x64

[TiffanyQTR]

Hi,
When running test 62 similar logic, exception was thrown as below:

Caused by: com.serialpundit.core.SerialComException: Can not get shared library spd2xxwinx64.dll resource as stream from sp-tty.jar file !

Opened archive, seems like the spd2xxwinx64.dll file is missing.

I'm running with Java 1.8.0_111. Tried both sp-tty from maven and this repo, neither worked. Let me know if I did anything wrong. Thanks!
