See #141

The preformance of this is approximately the same as the net.IP version,
except for the methods that return a network. For those, there is a
slight improvement.
This makes it easier to extend without adding many different lookup methods.
This is more ergonomic than creating a struct for a single value and
the performance is better as well due to less reflection:

BenchmarkDecodeCountryCodeWithStruct-8   	 1347441	       882.4 ns/op	       1 B/op	       0 allocs/op
BenchmarkDecodePathCountryCode-8         	 2708011	       445.1 ns/op	       1 B/op	       0 allocs/op
It is somewhat arbitrary, especially when dealing with switch statements
and code may be inlined for performance reasons.
In order to make it easier to refactor and optimize.
Slice length of 64 is used as most IPv6 trees will have that as their
maximum depth.
The comment on "iter" is because the linter was not stable and kept on
shifting it every time it ran.
And replace it with (*Reader).LookupOffset
To more closely match net/netip. Also, it may reduce confusion with
Networks and NetworksWithin, which refer to more than just the network.
