CloudComPy For Windows 10 - Anaconda3, Python 3.7 - August 30, 2021

The corresponding Anaconda3 configuration is described in the README.

The previous version (August 28, 2021) was a temporary fix to avoid a crash on calculation of cloud-to-cloud or cloud-to-mesh distances. The CCoreLib library has been fixed, this version is built with the latest CloudCompare sources.

ctest now detects premature program closure in Windows 10, so tests that crash are correctly detected as errors.
