chore(#29): Add data audit brac models

[lorerod]

Add data audit to BRAC dbt models

[lorerod]

@njuguna-n I implemented audits for both impact_pncview_visit and impact_pncview_expected_enrollments using only the macro compare_queries. Do you think using this macro is enough? Love to know your thoughts.
Also, will you want me to continue with all the PNC models? Or are you already making progress on those?

@lorerod & @njuguna-n, can you please support with answering the following questions:

• Is the approach started by @lorerod supporting the needs of this activity?
• What are the remaining models to audit?

Is the approach started by @lorerod supporting the needs of this activity?

I started implementing auditing macros using the 'audit_helper' package. This package's primary purpose is to help with the table auditing process and ensure that a refactored model provides the same output as the original one. Although it is not useful for the comparison we are doing now between couch2pg queries and cht-pipeline models, it will be helpful when we refactor existing models. However, as priorities changed, I decided to help Njuguna by providing a manual comparison of the widgets and data sources.

What are the remaining models to audit?

I only implemented three models, so much remains to be done.

To keep things organized, I'm going to separate this PR from the Data audit for BRAC models issue and initiate a new issue for audit for refactoring purposes. We can prioritize it for later.

[lorerod]

Also, I will make that issue related to the default models, not the BRAC models.

[lorerod]

Issue created. I will use this draft PR as an example of how to implement auditing on models at #80

[andrablaj]

@lorerod given the pipeline model changes, is this PR still relevant?

[lorerod]

This PR is not relevant anymore. Thanks, @andrablaj, for the cleanup.
