The reason is that in MSVC the long double type is identical to the double type. We should treat 64-bit long double as double. Modification to float is made for consistency.
* the function (in namespace detail) is split and two parts are renamed on purpose, because functionality is changed
* tests are added
* intersection.cpp split into new file intersection_integer.cpp
* testing point count now if specified
* Add missing headers so all header files compile independently
* Add github actions script to check if all headers compile independently
* Remove unused headers from algorithms (not detail) and core and fix headers in tests
* Fix typo in headers.yml and missing header in srs
