Setting lephare config from stage params

[raphaelshirley]

Waiting for other PRs to merge before merging to ensure config values consistent with updated string dict format

Closes #43

I want to wait for the lephare string dict changes and the COSMOS param defaults to merged before merging to ensure merge conflicts are handled correctly

Problem & Solution Description (including issue #)

The redshift grid was being read from the lepahre config which could be distinct from the stage params and cause a confusion. WE instead overwrite the lephare config from the params. This should allow the notebook to be sped up by setting a sparse redshift grid in the inform params.

This looks reasonable to me. But I would like to hear what Johann or Alex have to say about using log spacing for the zgrid.
