Fix the cabal examples so that they work

Handle fd/fdfind differense in run-stylish-haskell.sh just as the other
scripts do.

This makes it easier to analyse different runs, since all of them use
the same connection four tuples.

./network-mux/demo/ns-setup.sh is a generic script for running client
/ server applications using traffic shaping.  We can reuse it for
`tx-submission` demo.

WithBytes retains tx bytes for whole tx life time (e.g. until the
inbound side exits), avoiding it we can GC the bytes after decoding is
done and we extract the length of a tx.

This avoids re-serialisation cost to get the size, increases allocation
by storing bytes of the original `tx`.

Increased span of mini-protocol numbers.

* maximum number of txids to request
* unackwnoledged buffer size
