Better PyraFARM: simpler structures, lower building costs, best fit for Aquaponics vertical growing

This is a major upgrade for our PyraFARM design: (1) dimension increased from 12x48M to 48x48M; (2) lest structural materials used to achieve almost the same strength; (3) bubble foam flow simplified from 3 units for one module to 2 units with one to one pairing flow circuit; (4) Fish tank and grow bed alley now rotated 90 degree to fit a 6-meter width bay rather than the previous 4-meter width bay.
