Add Smartcard functions (RDV4.0) (#646)

* allow common makefile options-defines

* remove non-existing file references

* Uncomment lcd option (still) not enabled by default

use Makefile_Enabled_Options.common
to enable lcd if desired.

* Add Smartcard Functions

* add smartcard to menu + make get atr work

sc is now functioning as far as my limited knowledge takes me

* sc cleanup - add init to all sc commands...

because cmds won't work until the first init happens.  (multiple inits
don't appear to affect it negatively)

* default options to exclude Smartcard

for main repo

* update changelog

 ### Added
+- Added `sc` smartcard (contact card) commands - reader, info, raw, upgrade, setclock, list (hardware version RDV4.0 only) must turn option on in makefile options (Willok, Iceman, marshmellow)
 - Added a bitbang mode to `lf cmdread` if delay is 0 the cmd bits turn off and on the antenna with 0 and 1 respectively (marshmellow)
 - Added PAC/Stanley detection to lf search (marshmellow)
 - Added lf pac demod and lf pac read - extracts the raw blocks from a PAC/Stanley tag (marshmellow)
