Draft: Terminal warnings control

This MR handles the warnings that were displayed on the terminal.

Steps:

• ExpertApp: removed arguments that didn't exist on some widgets.
• ExpertApp: suppressed deprecation warning related to the Tool Manager constructor.
• Added dtype=object for a ndarray creation in the air_exchange method.
• Restricted the tornado version to 6.1 due to deprecation errors.

With these changes there are no warnings being triggered.
