can GenericJob be pickled or get by a hash value?

[appassionate]

waow! My pleasure to propose the first idea to pyiron_base :)
suppose there will be a more relaxed discussion environment than issue? iguess..

I believe GenericJob finished "serialization" using exsiting hdf5. Users can convieniently access every "Job" by a path.
I think it will be more convient to get such a job object in python by a recorded data structrue like:
recorded = {"hashed_code": {"job_name":"exmaple_job", "project_path":"/example/path"}}

maybe we can get a job by using such a function:

def get_job_from_recorded(hash_value, recorded):
    pr_path = recorded[hash_value]["project_path"]
    job_name = recorded[hash_value]["job_name"]
return Project(pr_path)[job_name]

There is another case that python object can be pickled by implementing magic method like this:

  def __reduce__(self, ):

      return (self.unpickle_J, (self.project, self.job_name))
  
  @classmethod
  def unpickle_J(cls, project, job_name):
      
      return cls(project=project, job_name=job_name)
