Add suggested session stop

[tiffanyona]

Include a trigger that indicates when the session should be stopped following the next criteria:

• Elapsed session time >45 min
• Reward consumption more than 1.5ml
• Last successful harvest choice + lick more than 2min ago.

This could either stop the session automatically or just a warning.

1 and 2 should be added to the schema as part of the task logic

Consider 3 as "Time since last reward" instead for now to be more general.

1 and 2 are bitwise or and 3rd is a AND gate
