Improve tag detection for Cyanogenmod HCE

[jekkos]

• It seemed that cyanogenmod random uids weren't properly detected by the mifare-desfire-version utility. I have added a check for random uid properly by checking for 08 prefix (as per the NXP spec) in the tag detection code
• Adapt Cyanogenmod SAK value (now the same as in the libnfc-nxp code), see
  https://github.com/CyanogenMod/android_external_libnfc-nxp/blob/cm-12.1/inc/phNfcConfig.h:277
• There's still a bug remaining in the code for parsing a random uid. I might want to create an issue for this

The following request/response to a Desfire Android app I'm building yields the following result

I have also disabled the ATS check for desfire to have my phone detected as a desfire tag. Think this change might be related to issue #17 here

[jekkos]

Maybe disabling the ATS check might not be the best solution here (as suggested already in the other referenced issue). However I do need some mechanics to detect my phone as a Desfire card (SAK + ATQA are set properly, but can't change ATS). If I leave this part out would you consider to accept the random uid + sak value change as pr?

It is probably less hackish to drop the detection code as proposed in #17. I'm on other projects ATM but would be happy to review a pull request for this 😉

This branch is not mergeable, so closing this PR.
