Badges are out of date!

For some reason the badges for build-test #297 for https://github.com/sony/nmos-cpp/commit/95536ae32341046dabf66286b373d70e97e3a59a have got lost, and the badges shown on the README.md actually reflect the previous commit. I cannot understand from the logs for the above build-test run why that is.

Those badges would have shown that all the tests FAILED because the Ubuntu 18.04 and 20.04 builds of nmos-cpp-node all seg faulted. :-(
