As a User I want to have both parse ary and parse stream options

[dimus]

Currently, gnpaser moved to use parsing by chunks instead of parsing a stream. This implementation allows to have the same order of input and output, but it is not good to using gnpaser as a "pipe in pipe out", because it collects names into a "buffer" until they are parsed, while pipe in pipe out approach sends and receives names one by one.

@LocoDelAssembly, for using pipes in Ruby code one in has to immediately return one out. In old code it was achieved by a stream that would take one name at a time instead of an array of names.

It is possible to avoid streaming method by reducing the size of a batch to 1. So I suspect we can close this ticket for now. An option for the batch size is added already.

The v1.0.0 code is located in 102-clean branch, an example of running 1 name at a time is

gnparser -b 1 "Pardosa moesta"

Looks like we need to have streaming option, because otherwise pipe solution becomes too hackish

It seems that b47531d
allows to close the issue again for now

Looks like we do need a stream. I have an expreimental package to order unordered streams, and I will try to use it here. https://github.com/gnames/gnlib/blob/master/organizer/organizer.go
