change pcap snaplen to 126 bytes
...
We really only care getting as far as the UDP header and can discard the rest. This should reduce load, and perhaps enable full pcap with ports on the BPF filter
UDP header = 8 bytes
IPv4 max size = 60 bytes
IPv6 fixed size = 40 bytes
Ethernet header size = 18 bytes

BREAKING: changes to CLI interface, moved to cobra CLI
...
To better support configuration and user friendliness, migrated to cobra based CLI. The source tree structure has also changed to single go module, the server has been renamed hypd and client has been named hyp. The original structure came into being organically, but now that the vision is more complete it's best to make these adjustments now.

rename hyp-client to hyp and upgrade internal dependencies
...
hyp-client is cumbersome. The server is called hypd, so it's fine if the client is just called hyp. Not only is it fine, it's better.
