Tilable 100 SPM factory blocks for Self building Mega Base with a 1000SPM research hub

This is a research hub for Factorio 2.0 with the Self building Mega base. It has a main hub for research where all science packs are delivered, and tilable 100 spm Blocks where Nauvis research is crafted then delivered by train to the main hub. Only have 300 SPM and want 100 more, pop in another Block. I determined this was the best approach as you can only have one landing pad by default per planet. and it was better to build an oversized research hub and bring science in than try to build one massive research base.
