v1.6.3 - Dep bump and better MAC address retrieval on Windows

Windows

• MAC address should now be properly retrieved when using VPNs (#108).

Linux

• Fixed an issue where after an abnormal process termination (like FATAL), Buddy would have to FATAL 2 times in a row before it can be started again, because the shared memory is not cleaned up automatically by Linux. Now Buddy will do the cleanup instead.
• Changed libprocps dependency in favor of libproc2.

Both

• Updated Qt framework version to 6.8.
