This PR replaces UnitTest-cpp with Catch. Catch is downloaded
using cmake's ExternalProject_Add and installed into the
include directory as it's a header only library.

Project files were not following the clang-format style. For people
using IDEs were clang-format is always run after a save this would
cause unwanted changes.
This commit only applies "clang-format -i" to files.
Now that the STL respects /W4, this test that uses std::copy_n to copy a span of ints to a span of chars triggers "warning C4244: '=': conversion from 'int' to 'char', possible loss of data". Switch the source & destination spans to short and int to maintain the test's cross-type nature but without narrowing.
