Add support for modular build structure. (#26)

* Make the library modular usable.

* Switch to library requirements instead of source. As source puts extra source in install targets.

* Add missing b2 testing module import.

* Add requires-b2 check to top-level build file.

* Bump B2 require to 5.2

* Update copyright dates.

* Move inter-lib dependencies to a project variable and into the build targets.

* Update build deps.

* Replace GHA CI with simpler working one based on alandefreitas/cpp-actions utilities.

* Move project global include to target local include.

* Only msvc gets minor version tests.

* Redo GHA CI to undo move to cpp-actions.

* Need specific python3 for systems where regular python is not 3.

* Can't assume a specific version of clang/gcc is installed.

* Undo explicit g++ compiler specification.

* Put back C++-03 testing.

* Put back C++-03 testing.
