M.2 M key socket
Hi,
adding symbol for M.2 socket with the mechanical key in the M position.
It looks like the official M.2 specification is not publicly available. However, I did find some bootleg copy here: https://wenku.baidu.com/view/e367f8e10912a216147929e7?pn=150 Pinout for the M key socket is on page 150.
