Add New khiops.core.api.check_dictionary Function #478

Description

The goal of this function is to have Khiops core check the dictionary (domain). To this end, a basic scenario of just opening the associated .kdic file suffices.

Questions/Ideas

• The function will return True if the check results in return code 0 and no warning and no error (neither on stdout, stderr, nor in the log). Otherwise, the function returns False and the errors and warnings are printed.
