Default's for MarkovConsumerType don't work.

[DominicWC]

Describe the bug The default constructor for the income distributions for MarkovConsumerType don't create unique distributions for each state, leading HARK to throw an error.

To Reproduce Run:

from HARK.ConsumptionSaving.ConsMarkovModel import MarkovConsumerType MarkovExample = MarkovConsumerType() MarkovExample.solve()

Expected behavior The model should solve without issue.

Markov Consumer Type also doesn't accept a time-varying Rfree like most other models do.
