Compatibility with igraph 2.0.0

[krlmlr]

@krashkov @afshinsadeghi: This package does not terminate its checks when run with the release candidate for igraph 2.0.0.

Is this a problem in your package? Should we be doing things differently?

Install the 2.0.0 release candidate using pak::pak("igraph/rigraph") .

We're planning to release igraph 2.0.0 on January 23. My sincere apologies for the short notice, I only realized today that I should have warned about the problem much earlier. Happy to postpone if it turns out that the problem is on our end. Thank you for your help!

Tracker: igraph/rigraph#989.
