S3 conflict with package "sf"

[cysouw]

As far as I have been able to track it down, there seems to be an S3 conflict between this package and the package sf.

Registered S3 methods overwritten by 'proxy':
  method               from    
  print.registry_field registry
  print.registry_entry registry

I don't know how many packages import both seriation and sf, but my package qlcVisualize does this, so this warning pops up every time it is loaded.

Everything still works, but it would be nice if this conflict could be resolved.
