Review week 38: farm

A greenhouse became a farm. For review:

• Food planning: project the harvest per hour from game data, subtract the demand, range in full hours with floor.
• Light cycles: one counter per tick, light below the light limit, a second counter for the cycles. Registers do not survive a restart.
• Health: Efficiency is a product of breathing, light, temperature, water and pressure. Causes with priority: check the least important first, overwrite with select.
• Many trays: −1 of empty trays falsifies Minimum and Average. For the weakest tray each needs a name, the hashes sit in a table in the stack.
• Alarms: collective alarm, code on the display, klaxon until acknowledged with a remembered code.
