This allows for more flexibility without requiring adding a method to Reader for every possible variant.

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.
