`webgraph analyze dissect`

[zommiommy]

We should update and introduce the dissect tool written by Davide: https://github.com/colobrodo/webgraph-tools/blob/main/src/dissect/dec_stats_and_count.rs

Maybe it can be part of webgraph analyze codes as we alreay compute that information.

Currently, we only print the size of each part using the top-k optimal codes, not the "current" codes
