New section breaking down the 5 condition families (OTHER / ZONE /
CTRL / TIME / SEC) with their bit layouts, worked examples, and a
Python usage block showing Condition.decode and Program.condition().
Removes the corresponding entry from the "what we don't yet know"
list.
Also rewords the ProgramCond table to point at the new section
instead of saying the bit split is unknown.
