Moved the ColecoVision, Atari 5200, and Vectrex into their own generation as they were a new generation beyond the Atari 2600. The 5200 was obviously a next generation followup to the 2600 and the ColecoVision was advertised as "third generation" by Coleco itself (https://flashbak.com/wp-content/uploads/2015/11/flashbakcoleco2.jpg). Updated the subsequent generation numbers accordingly.
