ccitt: style fixes This commit applies some style fixes raised in the https://go-review.googlesource.com/c/image/+/194417 "ccitt: set bitReader default order to MSB" review. Having nextBit return uint64, not uint32, removes some type conversions. Removed a redundant "& 1" computation. Updated a comment with s/LSB/MSB/, missed in the previous commit. Restored the semantics of the "nBits" variable. Throughout the package, there are a number of times where we use paired local variables or paired struct fields, named "bits" and "nBits". The semantics is that "bits"' type is uint32 or uint64 that actually holds a variable number of bits, and "nBits" is that variable number. The previous commit, writing MSB-first instead of LSB-first, changed the semantics (without changing the variable name) so that one of those "nBits" variables now held the index of the next bit, not the number of bits. This commit restores the semantics: the shift is (7 - nBits), not just nBits.
