Linking test-regression2 fails with "relocation truncated to fit:
IMAGE_REL_AMD64_REL32 against `.rdata'" once its object grows past what
the MinGW linker copes with, and the copy constructor's helpers push it
over: the object grows by 6.3%, from 4,654,128 to 4,944,920 bytes at -O0,
and develop links at the smaller of the two.
Building the tests optimized shrinks the object enough to link, but the
binaries clang 11.0.1 and clang 18.1.8 then produce crash before doctest
prints its first line - 39 of 102 tests on clang 18 - so the objects have
to become smaller rather than denser.
Moving the test cases that follow "regression tests 2" into a file of
their own brings that object to 4,687,888 bytes, which is 0.7% above the
size that links today rather than 6.3%. Both files still build for C++11,
C++17 and C++20, and run the same 9 test cases and 135 assertions as
before, now spread over two binaries.
New regression tests belong in unit-regression3.cpp from here on, which
is what CONTRIBUTING.md now says.

The library does not preserve the insertion order of object keys. There
are frequent requests to change the library in this aspect. The README
and the contribution guidelines now contain links to containers that
can be used to replace std::map to preserve the insertion order.
This introduces a clear separation between test data and test
binaries. Test data is moved into test/data, and the test binaries
move into test/src. A new CMake script specific to building the
tests is introduced in /test to slightly clean up the toplevel
one.
As well as tidying things up, this makes the next step trivial...
