firmware version

According to http://wiki.radiowar.org/Proxmark3%E5%9B%BA%E4%BB%B6%E5%88%97%E8%A1%A8
firmwares newer than 617 have problems.

Google translated version

Please do not upgrade your firmware to the CDC Proxmark3 version r617 ~ r830 driver's! We found that because the problem will lead to Proxmark3 code appears unable to identify high-frequency card, and 816 will appear after Nested number of keys for 000000000000.
