Pull request description:

  ### Description

  Not much to say besides that I bumped some version which helps us to resolve some dependency hell :)

  ### Notes to the reviewers

  `ahash` was previously fixed because of an incompatibility with the defined MSRV. The MSRV has been bumped to 1.56 so we can update the dependency.
