Adding remaining non scripted Molex connectors to new repo
There where 5 non scripted connectors remaining in the old Connectors_Molex repo.
Two coaxial connectors and 3 FFC series connectors. (The later are not part of pull request https://github.com/KiCad/kicad-footprints/pull/107. That pull request adds dual row connectors, These FFC connectors are single row.)
No functional changes to the footprints. Added second reference and pin 1 markers where necessary.
