[A&R Feature Request] Create an API to pull park access advisories into the attendance and revenue system as variances.

[sallyhaynes]

Description: We have a data set of park closures/ access changes run by Rob Fiddler that we would like to pull into A&R as variances. These come from the staff advisory portal & bcparks.ca.

Context: All park access changes and closures affect attendance at parks. They currently need to be added manually as a variance notes but are often missed (POs often think if an area is closed they don't need to add any info for it in the A&R system). Pulling in this data will automate a large percentage of variance notes and help explain data anomolies.

Links to other resources/docs:

Rob's wildfire closure spreadsheet made from an API pulling from CMS. He said he can build us a spreadsheet that includes all closures.

Staff portal:

We would like the advisories to export as variance notes (would show in both regular & variance export), and if possible, be viewable in the data entry screen.
