Logger level should not be set

[coezbek]

It is customary for Python packages to not set the log levels, but let library users decide which logging to enable.

At least NeMo-text-processing shouldn't override if users have disabled logging from NeMo.

So instead just setting the level to INFO:

NeMo-text-processing/nemo_text_processing/utils/logging.py

Lines 18 to 23 in e15caea

	logger = logging.getLogger("NeMo-text-processing")
	c_handler = logging.StreamHandler()
	logger.addHandler(c_handler)
	logger.setLevel(logging.INFO)
	logFormatter = logging.Formatter(fmt=' %(name)s :: %(levelname)-8s :: %(message)s')
	c_handler.setFormatter(logFormatter)

At least it should be:

if logger.level == logging.NOTSET: 
    logger.setLevel(logging.INFO)

This would honor logging configuration set before the library is loaded to suppress logging output printed during initialization.
