Each header block contains a Required Insert Count, the lowest possible value
for the Insert Count with which the header block can be decoded. For a header
block with no references to the dynamic table, the Required Insert Count is
zero. For a header block with references to the dynamic table, the Required
Insert Count is one larger than the largest Absolute Index of all referenced
dynamic table entries.
