My suggestion would be to drop the idea of trying to
compress the lnotab in clever ways, and just make it
a straightforward list of bytecode offset/line number
pairs. I can't imagine that the size of an uncompressed
lnotab would be a problem in this day and age.

If ordering is an issue, generate it internally as a
dict and convert it to a sorted list on output.
