Automate Botania Pure Daisy block placement

--place turtle at bottom left side of the expected layout
--place logs or stone in slot 1
--place result in slot 16
-- Main program will automatically places blocks in a 3x3 square and leave out the middle then returns to start position and will mine up the new block once transformed
