Update the lightning graph snapshot used in benchmarks

Browse source 
The previous copy was more than one and a half years old, the
lightning network has changed a lot since!

As of this commit, performance on my Xeon W-10885M with a
SK hynix Gold P31 storing a BTRFS volume is as follows:

```
test ln::channelmanager::bench::bench_sends                                  ... bench:   5,896,492 ns/iter (+/- 512,421)
