Add total # of unique notices grouped by severity

[emmambd]

Describe the issue

Right now, the total # of errors, warnings, info, etc seems to be a sum of the number of occurrences of notices with that severity.

Instead, it should be the # of unique notices. For example, in the dataset below, the error count should be 2, not 39399.

Why?

Validator users have consistently given feedback that the number of occurrences is overwhelming, and sometimes a deterrent for producers to actually fix issues, since it isn't clear that they can often fix thousands of occurrences with 1-2 changes. We want to highlight the unique number of validation notices triggered instead to reduce overwhelm and indicate the diversity of problems within a dataset.

Occurrences can be added in the future, and should be included per notice, e.g block_trips_with_overlapping_stop_times total_occurrences is 4.

Steps/Code to Reproduce

Go to Swagger: https://mobilitydata.github.io/mobility-feed-api/SwaggerUI/index.html#/

Use mdb-10-202402080058

In /v1/datasets/gtfs/mdb-10-202402080058

  "total_error": 39399,
   "total_warning": 1486333,
   "total_info": 11,
   "url_json": "https://files.mobilitydatabase.org/mdb-10/mdb-10-202402080058/report_5.0.1.json",
   "url_html": "https://files.mobilitydatabase.org/mdb-10/mdb-10-202402080058/report_5.0.1.html"

Expected Results

  "total_error": 2,
   "total_warning": 11,
   "total_info": 1,
   "url_json": "https://files.mobilitydatabase.org/mdb-10/mdb-10-202402080058/report_5.0.1.json",
   "url_html": "https://files.mobilitydatabase.org/mdb-10/mdb-10-202402080058/report_5.0.1.html"

Actual Results

In /v1/datasets/gtfs/mdb-10-202402080058

  "total_error": 39399,
   "total_warning": 1486333,
   "total_info": 11,
   "url_json": "https://files.mobilitydatabase.org/mdb-10/mdb-10-202402080058/report_5.0.1.json",
   "url_html": "https://files.mobilitydatabase.org/mdb-10/mdb-10-202402080058/report_5.0.1.html"

Proposed Solution

Add unique_error_count, unique_warning_count, unique_info_count so it's clear what is being described.
