NetworkX 3.0 support

[prayerslayer]

• TSPLIB 95 version: 0.7.1
• Python version: 3.10
• Operating System: macOS

Description

Tried to install this library, can't because I want to use networkx 3.0+ in the rest of my code.

What I Did

pip install

Thoughts

Is there a specific reason not so support current networkx versions? A cursory search of the repository suggests that it is only used here, and those calls seem compatible to the current API too.

I've addressed this in my fork of this repo, which is packaged with another library I maintain called pylkh.

pip install lkh==2.0.0 will install my fork of tsplib95 as well as the lkh package.
