Lipd Attribute Error with pyleo.utils.jsonutils.json_to_PyleoObj()

[pgc2113]

An AttributeError occurs when you convert a json file to PyleoObjct. I ran some wavelet coherence analyses using Pyleoclim and wanted to save the results as json. I tested converting the json file to PyleoObjct and it results in an AttributeError stating that module 'pyleoclim.core' has no attribute 'Lipd'.

To Reproduce (Generic Example)
import pyleoclim as pyleo
ts = pyleo.utils.load_dataset('SOI')
pyleo.utils.jsonutils.PyleoObj_to_json(ts,'test.json')
pyleo.utils.jsonutils.json_to_PyleoObj('test.json', 'Series')
Expected behavior
I would expect that the json file be converted to a pyleo.Series object, or in my specific case, a pyleo.Coherence object.

This module was originally developed to support the AI work on PaleoTS. Since the scope of this project has significantly changed, json utilities outside of the Series object is not supported.

Looking for someone who can take this one.
