ILX511 CCD Interface r2

I previously posted my ILX511 CCD Interface for the ICE40 here. I received the board and brought it up, there were several stupid issues that required rework (most significantly I had Vdd and Vss the wrong way round in one place!). This version of the board fixes those issues. Kicad files/gerbers here. There maybe another update if this design also requires some hacks…
