This can reduce many `peek(stream.input, i)` in the source code and improve readability.
Here we use abstract type & subtyping because it's common traits pattern
in Julia.
We do not need to export these objects because we can use strings for
versions in user-facing functions like:
```julia
function load(str::AbstractString; version::YAMLVersion)
# ...
end
function load(str::AbstractString; version::AbstractString)
version == "1.1" ? load(str, version=YAMLV1_1()) :
version == "1.2" ? load(str, version=YAMLV1_2()) :
throw(ErrorException())
end
load(str, version="1.1")
```
