Support C++20 in binary wheels
- Use Casacore 3.6.0 for the binary wheels.
- Use newer Boost version for the binary wheels, since the default Boost version is incompatible with C++20. (It uses deprectated C++ features.)
- Hide Boost from Casacore, so Casacore does not build its tests, especially tests that require an even newer Boost version.
- Use Python 3.12 image for building binary wheels.
