dataset scope should come from dune.dataset_name

[dougbenjamin]

If dune.dataset_name is defined in the meta data file then get the dataset scope from that variable.

Use the namespace value to define the file scope if defined.

suggested code is in - PR#57

This is ostensibly already implemented in the sample dune module:
https://github.com/fermitools/declad/blob/main/declad/custom/dune.py#L158
Have you updated the custom/dune.py in your configuration?

Nevermind, I wrote the previous before I read the patch.

would you kindly create a new tag 2.3.5 and update the version file
