enh: Also raise error if log_level is above default

[hoxbro]

It can be hard to debug why something is failing with die. This makes it so that when you have a higher log level than the default, it will raise the exception.

Default is WARNING:

panel/panel/config.py

Lines 261 to 263 in 321d116

	_log_level = param.Selector(
	default='WARNING', objects=['DEBUG', 'INFO', 'WARNING', 'ERROR', 'CRITICAL'],
	doc="Log level of Panel loggers")
