#region RFC2435 Length Field
/*
The Length field is set to the length in bytes of the quantization
table data to follow. The Length field MAY be set to zero to
indicate that no quantization table data is included in this frame.
See section 4.2 for more information. If the Length field in a
received packet is larger than the remaining number of bytes, the
packet MUST be discarded.
When table data is included, the number of tables present depends on
the JPEG type field. For example, type 0 uses two tables (one for
the luminance component and one shared by the chrominance
components). Each table is an array of 64 values given in zig-zag
order, identical to the format used in a JFIF DQT marker segment.
For each quantization table present, a bit in the Precision field
specifies the size of the coefficients in that table. If the bit is
zero, the coefficients are 8 bits yielding a table length of 64
bytes. If the bit is one, the coefficients are 16 bits for a table
length of 128 bytes. For 16 bit tables, the coefficients are
presented in network byte order. The rightmost bit in the Precision
field (bit 15 in the diagram above) corresponds to the first table
and each additional table uses the next bit to the left. Bits beyond
those corresponding to the tables needed by the type in use MUST be
ignored.
