Writes the given byte to the output, writes an extra zero if byte is 0xFF.
This method is "careless" - caller must make sure that there is enough
space in the output buffer. Emits up to 2 bytes to buffer.

Returns the DC diff or AC value for extra bits value x and prefix code s.

Table F.1 – Difference magnitude categories for DC coding
SSSS | DIFF values
------+--------------------------
0 | 0
1 | –1, 1

3 | –7..–4, 4..7

CCITT Rec. T.81 (1992 E)
Table F.2 – Categories assigned to coefficient values
[ Same as Table F.1, but does not include SSSS equal to 0 and 11]
CCITT Rec. T.81 (1992 E)
F.1.2.1.1 Structure of DC code table
For each category,... additional bits... appended... to uniquely identify
which difference... occurred... When DIFF is positive... SSSS... bits of DIFF
are appended. When DIFF is negative... SSSS... bits of (DIFF – 1) are
appended... Most significant bit... is 0 for negative differences and 1 for
positive differences.
In other words the upper half of extra bits range represents DIFF as is.
The lower half represents the negative DIFFs with an offset.
