fixed division, undefined behaviors and some improvements (#33)
* testing using ctest
* emove old testing script
* added github workflow CI
* updated CI
* added unit test for macros
* F16() and F16C() are both rounding allways, so fix16_from_dbl should as well
* added tests for strign operations, but these functions are in my opinion unreliable and tests are failing
* removed old unittests
* removed old unittests from cmake
* problem with division using gcc
* improved benchmark
* clarification of problem with division
* attempt to fix
* fixed some undefined behaviors, fixed division
