Since compiling times became unbearable (75 sec), I split up the file
into standalone subfiles which I only compile once (without biber). They
compile in around 10 seconds, which is still a lot, but it is bearable.

In Dyon, a variable can be marked as outliving another one. I can’t see
how this is relevant, though. I don’t understand exactly how it works
but it seems to just increase a reference count/test that variables are
put on the stack in the right order, since there are no references. It
also seems to have non-local effects, which is double-plus-ungood.

These seem to not work and I don’t know why, so they are commented out
for now.

Also change unique->exclusive

Also switch to argparse for correct parsing of arguments and help

Also update to \inline.
