Digi-key part for ordering

[max1220]

In the linked eevblogs post[1], the poster found a digikey partnumber(H122178CT-ND) of a fitting female connector, with a minimum order quantity of 1. Maybe add that to the README, so if you want to build a project using this keyboard, you can buy the right part.
