Rusty Russell 120c9d8ce4 devtools/gossmap-compress: generate better scids. ...

Our poor scid generation clashes badly with simplified hashing (the
next patch) leading to l1's startup time when using a generated map
moving from 4 seconds to 14 seconds.  Under CI it actually timed out
several tests.

Fixing our fake scids to be more "random" reduces it to 1.5 seconds.
