Find a way to prefix 3rd-party includes indicating source library

[jerinphilip]

There's a translator folder in bergamot-translator and also 3rd-party/marian-dev. When files are included, it's not obvious which folder the sources came from, and leaving it thus can potentially lead to issues. For example, below file which includes translator from both marian and bergamot-translator with no way to distinguish on first look.

bergamot-translator/app/marian-decoder-new.cpp

Lines 11 to 15 in f89c989

	#include "translator/output_collector.h"
	#include "translator/output_printer.h"
	#include "translator/parser.h"
	#include "translator/response.h"
	#include "translator/service.h"

While this file is not strictly necessary here, this should ideally be configured so that the source-library is known, in this case 'marian' or 'bergamot-translator'. Unsure of the solution, but filing an issue.
