Add Avalonia PacketLogger sample

[Rutherther]

This should be created in a separate repository, support for both remote and local should be added as well as support directly in Direct3D (if possible) and usage in existing Avalonia application should be possible.

Feature set:

• Packet sending
• Packet receiving (once, in intervals, support for multiple packets)
• Filtering what packets you see (and still saving all of them)
• Saving to file with multiple formats (with or without time, with or without Recv and Send) and filtering
• Auto saving
• Packet blocking (regex filter)
• Easy packet replacing (filter for packet header, position, then set another position)

[Rutherther]

• Injection to multiple NosTale clients
• Communicate using named pipes with NosTale, be a separate application
• Show packets from files, allow filtering and saving

v2 features:

• analysis of packets (form client and files)
  • split packets by fields, allow defining what field is what type, name...
  • generate NosSmooth packet files
  • show packets matching the header to easily compare arguments of the packets to ease the work when figuring out fields of a packet

[Rutherther]

• save filtering profiles, keep the last profile upon restarting the application
