Core methods for decoding blocks of docs / freqs / positions / offsets.

• Read count longs.
• For all i >= 0 so that bShift - i * dec > 0, apply shift bShift - i * dec and store the result in b at offset count * i.
• Apply mask cMask and store the result in c starting at offset cIndex.

Throws:

IOException
