RE the current constant values in https://github.com/cevatbarisyilmaz/lossy/blob/master/lossy.go, it would be nice if there was some documentation that explained the derivation of these constant values.

Hello, you can check the minumum and maximum header size for IPv4 here https://en.wikipedia.org/wiki/IPv4#Packet_structure
in the secition for Internet Header Length. And for IPv6 here: https://en.wikipedia.org/wiki/IPv6_packet#Fixed_header

Rest of the UDP values are just the addition of UDP header size (8) to respective IP header sizes. https://en.wikipedia.org/wiki/User_Datagram_Protocol#UDP_datagram_structure

Will improve the documentation in the future. Feel free to create a PR yourself as well.
