// Params
//    hotswap: default is false
//      if true, will include holes and pads for Kailh choc hotswap sockets
//    reverse: default is false
//      if true, will flip the footprint such that the pcb can be reversible
//    keycaps: default is false
//      if true, will add choc sized keycap box around the footprint
// 
// note: hotswap and reverse can be used simultaneously
