The wrapping of the log_it function has been added, a test has also been added for the fact that it works

Added check of return values ​​and call exceptions. The call to the install logging level function from libdap_python_mod is also executed.

The problem with the names was fixed, the library itself is now called libdap_python_module. The libdapConnector.py file was also created, which contains the dap class, and is responsible for working with libdap_python_module. Fixed CMake file so that subprojects are built with the -fPIC flag. Until I learned to collect dynamic libraries and set certain parameters in CMake. Also added that when cmake is running from the src directory, it copies the file libdapConnector.py.
