// readHuff reads Huffman table from data starting at off into table.
// Each entry in a Huffman table is a pair of bytes.
// The high byte is the encoded value. The low byte is the number
// of bits used to encode that value. We index into the table
// with a value of size tableBits. A value that requires fewer bits
// appear in the table multiple times.
// This returns the number of bits in the Huffman table and the new offset.
// RFC 4.2.1.
