[MiniDNS][DIY] Build DNS Protocol Implementation

[DIY Route Only]

Build out the base DNS protocol implementation

Here, we write the base protocol implementation - capable of encoding and
decoding the foundational DNS constructs:

* Packet - The DNS Packet itself, holds the Header, Questions, Answers, Authorities and Additionals
* Header - The DNS Packet Header
* Name - Representation of a DNS Name, with logic for handle DNS Name compression/pointers
* Question - Representation of a DNS Query, holds the name, type and class of the Query.
* ResourceRecord - Represents a single Record in a Result[1].

[1]: This one may be skipped, with the Record object instead implementing this piece.
