Requirements files for package versions

[geo7]

Having the versions of packages used for the book in a requirements.txt would be helpful for others reproducing things a year or so down the line.

Looking through the repo for something such as numpy doesn't bring up anything wrt the version used, just that it's imported in several locations.

As this book was only recently finished, perhaps there's an environment on the authors computer which has all the correct package versions within it? And a file could be generated from that.
