Added SIM_Card_Shielded_CD
This is a generic SIM card holder symbol, based on "SIM_Card" and "SIM_Card_Shielded". All the violations are inherited from the previous two symbols and are left like that, in order to have library consistency.
Examples of real-world products that could be used with this symbol are:

- and many others...
I used this symbols for this footprint: kicad-footprints!3506
The are some things that could be considered before merging:
-
While some SIM card holders use only 1 card detect pin, other have 2 card detect pins. Those with 1 pin usually work by closing/opening the connection from CD to GND. Those with 2 pins work by closing/opening the connection between the two CD pins.
-
Some card detect circuits are normally open when no card is inserted, while others are normally closed when no card is inserted.
-
Also some SIM card holders have 7 instead of 6 SIM card connections. This symbols has 6, like the other symbols in the library.
Based on 3 points above, some alternative names could be give to the symbols:
- SIM_Card_Shielded_CD (current one)
- SIM_Card_Shielded_1CD (meaning 1 card detect pin)
- SIM_Card_Shielded_6P_CD (meaning 6 SIM card pins)
- SIM_Card_Shielded_6P_1CD (combination of the last two)
- SIM_Card_Shielded_6P_1CD_NO (normally open when no card)
- SIM_Card_Shielded_6P_1CD_NC (normally closed when no card)
