Description

split off #46

Fix #43

Fix #39

WILL ALSO NEED TO FIX IN THIS MINOR COMMENT LINKED BELOW FROM #46

We also need one where a warning is thrown when this happens:

log = get_logger("name", stream_handler = True)

new_log = get_logger("name") # Will grab the correct logger

new_log_extra = get_logger("name", stream_handler=True, rich_handler=True) # this will get the correct logger, but not add the rich handler. This should be checked when performing this function and be made explicit..
