HFI: Download PDFs for Specific Zones and Not All Zones in a Fire Centre

**As a** FBA

**I need** to be able to Download Calculations for Specific Zones and Not All Zones in a Fire Centre

**So That** I can share related information to the Fire Crews and that I can print off for situational awareness.

**Acceptance Criteria**
- [ ] Given (Context), When (action carried out), Then (expected outcome)

**Definition of Done**
https://github.com/bcgov/wps/wiki/Definition-of-Done

No files, tests, or entry points are named. First clarify the missing Given/When/Then acceptance criteria and how specific zones within a fire centre should be selected and downloaded; done means the agreed behaviour is implemented and the Definition of Done at the linked wiki page is satisfied.
