Doesn't work after upgrading to Ruby 3.1

[sixtyfive]

I believe this has something to do with Psych 4.0.4 (ruby/psych#487 ?). Just changing rehash.rb line 256 to use #safe_load is not enough and I'm not sure which permitted_classes need to be specified (for me personally, YAML.safe_load(f, permitted_classes: [OpenStruct, Pathname]) worked).

Backtrace:

@sixtyfive @cirdes Thanks for the reports! I will be making time to address this issue, as well as make the internal architecture more future proof.
