Right now, the action to check that the version has been updated only checks the package version in init.py. It should now do the following:

• Save the version of eedl it gets from PyPI to an environment variable.
• Check init.py's version against that same variable using a similar method to what it's doing now
• Check the setup.cfg version by getting it via grep (Nick has some code in another action to just pull the version number via grep). May need to parse these as versions, not as strings.
• Optionally, check the actual formatting of the version numbers so that we know we're not doing things like '.09', which I do put in my versions out of habit.
