pkgs/profpatsch/netencode: add shallow parser

The “shallow” parser uses the fact that every netencode value is
length-encoded (or a scalar with a fixed length).
It does not need to parse the inner values in order to get the
structure of the thing.

That means that we can implement very fast structure-based operations,
like “take the first 5 elements of a list” or “get the record value
with the key name `foo`”.

We can even do things like intersperse elements into a list of values
and write the resulting netencode structure to a socket, without ever
needing to copy the data (it’s all length-indexed pointers to bytes).
