use of dreadl0ck/gopacket produces duplicate symbols #4

Commit https://github.com/dreadl0ck/ja3/commit/3e0281e06aec688b978e2def1373faec3e4d21a3 broke my code. I use google/gopacket for my own analysis, and dreadl0ck/gopacket is producing conflicts.

When I try and run my code, I see 

duplicate symbol '_pcap_wait' in:

I'm trying to use dreadl0ck/ja3 as an import in my own code.

Hi there,

sorry for late reply, I was very busy and didn't catch up with my mail.

I've reverted back to using google/gopacket on master with commit 64f6bac, and will use a different branch for the version with my gopacket fork in the future.
