tests: ensure version numbers in README are always up to date

mgeisler · mgeisler · commit 827ed2e58531 · 2019-03-30T11:20:14.000+01:00
This adds a test that will check the examples in README.md for the current package version. It also checks that there is a Markdown heading mentioning (at least) the current version. This serves as a simple check that the change log section is updated when the version number is bumped. Related to #30, #41, #47, and #48.
