Add support for graduating undergraduate dual majors & relax program checks

[mark-dce]

OVERVIEW

Over the past six months, we have refactored and tightened up the
code that determines ETD publication eligibility. Emory has also introduced
new dual degree programs and asked us to relax checking at the program level.

We currently match the program provided in the registrar data to the corresponding
degree entered by the student. While registrar data includes degree information after
the student has graduated; only the program information is available prior to
graduation to help us determine whether the ETD is in a pending-graduation state.

Based on these changes, the code in this PR implements the following business rules:

RULES

1. For each approved ETD
2. Look for an exact match of PPID, school, and program (do this first since this is the most efficient form of lookup and works 90% or more of the time)
3. If no exact match is found, look for a match of PPID & school (less efficient)
4. If no student & school match found, look for a dual major match (“UBUS” vs. “UCOL”)
5. Extract the graduation date from the best match (exact, or school, or dual-major in that priority)

ACTION

7. If there is an exact match, and a graduation date is present, publish the ETD
8. Otherwise, if there is a school match, and a graduation date is present, publish the ETD and log the program mismatch
9. Otherwise, if there is an undergrad business match, and a graduation date is present, publish ETD and log the student provided school and program
10. Otherwise, DO NOT PUBLISH the ETD and log any registrar records matching the PPID but not meeting graduation criteria (wrong school or pending graduation)

NOTE: this change also reformats the order of columns in the fixture data so relevant debugging and testing data is closer to the beginning of each record.

MORE BACKGROUND

ISSUE 1
Emory would like these student to list themselves as being part of
the "Emory College" program, but the Registrar is showing their
graduation record associated with the "Undergraduate Business" school.

This means the application expects to find a graduation record like
PPIDxxx-UCOL-BBA, but the Registrar data provides PPIDxxx-UBUS-BBA.

There are other students graduating in "UCOL" programs, so we can't
just change the mapping; we have to add an additional check for this
specific case.

It's also possible that they've listed their non-business degree, so we also
have to allow for program-vs-degree mismatches.

SOLUTION
This commit adds a secondary check when-and-only-when the student
has entered "Emory College" and also scans
Registrar data for the same student within the "Undergraduate
Business" program. In these cases, the program in the registrar data may also
not match the degree the student has entered because the student has
written the thesis as part of their liberal arts program instead of the business
program.

ISSUE 2
Emory has indicated that they would like to process graduation records
and ETD publication even if the student provided degree does not
exactly match the program data in the registrar data.

SOLUTION

• When an exact match cannot be found, look for student and school matches
  ignoring program & degree mismatches
• Use graduation status from exact matches when possible; otherwise, use
  relaxed matches if present, and log the differing data
• Relax program checking for undergaduate dual degree candidates in the
  same way
