Subject: [PATCH] Replace `using namespace` in headers with explicit
 namespaces.

As part of:
https://github.com/lancaster-university/codal-microbit-v2/issues/240

Other targets should also apply patches like
bdfa1eca85dbbd6fc8aaf5fc4c3fd00c1f65762d to ensure they don't
depend on the header files having the `using namespace codal`
line.`
