65 in a block whose file offset falls within the range
83 [offset of filter 0] : 4 bytes
84 [offset of filter 1] : 4 bytes
85 [offset of filter 2] : 4 bytes
87 [offset of filter N-1] : 4 bytes
89 [offset of beginning of offset array] : 4 bytes
92 The offset array at the end of the filter block allows efficient
93 mapping from a data block offset to the corresponding filter.
