Decode the string-to-key count for iterated and salted S2Ks

We need this for decryption.  From RFC 4880 [1]:

  The count is coded into a one-octet number using the following
  formula:

      #define EXPBIAS 6
          count = ((Int32)16 + (c & 15)) << ((c >> 4) + EXPBIAS);

  The above formula is in C, where "Int32" is a type for a 32-bit
  integer, and the variable "c" is the coded count, Octet 10.
