Subject: [PATCH] Remove include/boost/gil/version.hpp file as unused

Motivation:

  - GIL is part of Boost collection, so Boost version is sufficient
  - GIL version makes little sense unless GIL becomes independent
  - Two distinct version numbers, Boost's and GIL's, are confusing.
  - Role of GIL's version number is not documented thus not entirely clear

The removal was discussed and agreed upon in this thread
https://lists.boost.org/boost-gil/2019/11/0346.php
