Handle unexpected dates

[xmedr]

Overview

There were parsing errors coming from unexpected inputs in the termDate field. Examples of these inputs are 03312022, 0130/22, Not req'd to submit, on-going, or 045/15/21. This branch:

• handles the first two cases, by formatting them as month/day/year
• handles the cases with words, by making them lower case for standardization sake, and passing them through
• notifies the user of the last case, but passes it through as is

Testing Instructions

• Run make lm20.db and check for errors along the way
  • The process runs in github actions and this might be enough to satisfy this test
