CloudComPy For Linux 64 - Anaconda3, Python 3.9 - April 9, 2022

This version brings the following features:

• Update to CloudCompare 2.12.0 (april 7 2022)
• Add access to plugin RANSAC_SD on Windows and Linux (issue #27). See test035.py.
• Cross-section methods (issue #27). See test036.py
• Extract Connected Components (issue #27). See test037.py
• fix tests, activate trace on all tests to improve debug
• add methods on primitives
• fix a bug in conversion from C++ to Python, where objects name are missing.
• fix keyword arguments problems when default value is nullptr
• update README files, and add them in binary.
• fix several mistakes in doc

Remark: the large size of the file is due to the change of compiler (gcc instead of clang). The plugin RANSAC_SD does not work properly when compiled with clang... One way to obtain lighter files is to remove the debug information from the binaries. To be tested with the next release.
