Fixed circularity issues for CO and MO

  Bug fix

  This is to fix the circularity errors mentioned in issue #64

What this fixes and how it's fixed

The main problem was from the state_income_tax variable.

CO fixes:

• Changed out the tax variables to be more consistent with the 2022 worksheet found here.
• Switched out variables that reference current income tax such as state_income_tax for variables that reference last year's .

MO fixes:

• Changed state_income_tax for prior_year_state_income_tax_paid to break the circularity.

For both CO and MO I updated the baseline unit test variables to reflect those used in formula definitions.

@mitchellpound. This looks great. I ran all the test locally on my machine as well. Everything passes. I submitted a PR to your branch that updates the version in setup.py and adds new entries to the CHANGELOG.md and changelog.yaml files. Once you merge that into your branch, I'll merge this PR.

@rickecon Thanks! Just merged in your PR with the version and change log stuff.
