I noticed that increasing mu a little bit sometimes made a big difference,
because by completely ignoring fees we were choosing the worst of two channels
in some cases.
Start at 1% fees; this saves a lot on initial fees in this test!
Here's the new stats on mu levels:
96 mu=1
90 mu=10
41 mu=20
30 mu=30
24 mu=40
19 mu=50
22 mu=60
8 mu=70
95 mu=80
19 mu=90

Changelog-EXPERIMENTAL: `askrene` is now better at finding low-fee paths.
Any file in this directory which is executable and whose name only
consists of alphanumeric characters, space, '.', '-' or '_' will be
automatically loaded when lightningd starts (unless suppressed with
commandline options).
