As an API consumer
I want to be able to get PNRs
So that I can view the current state of the PNR zones

Given pnr_service.rs is responsible for managing PNRs
When getting a PNR
Then use get_pointer in pointer_service.rs as an example
And use update_pnr in pnr_service.rs as an example
And accept a name as a parameter to lookup the resolver_address
And use the resolver_address to get the resolver pointer
And use the resolver pointer target to get the personal pointer
And use the personal pointer target to lookup the PNR zone chunk
And then return the PNR zone chunk as a PnrZone
And refactor update_pnr to share the same function to resolve the personal address pointer from the name

Given pnr_controller.rs handles REST request for PNRs
When updating pnr_service.rs
Then also update pnr_controller.rs to reflect the new GET operation
And use put_pnr in pnr_controller.rs as an example
And use URL format GET /anttp-0/pnr/{name} where name is the PNR name used to define the resolver address

Given /lib.rs is responsible for integrating REST controllers
When updating pnr_controller.rs
Then also update /lib.rs to reflect the new GET operation
And place the new get_pnr function within the primary section where uploads_disabled can be true or false
And update openapi paths to include get_pnr

Given the postman collection reflects the REST endpoints
When updating pnr_controller.rs
Then also update the postman collection to reflect the new GET operation
And ensure it is added directly after the create and put operations
And update the associated /test/postman/README.md
And use newman to confirm both the collection and the new put_pnr endpoint work as expected

Provide unit tests where applicable for new code.

Implementation Notes

- Place any unit tests at the bottom of the same file as the associated production code
- Increment patch version of anttp package in Cargo.toml
- Create a copy of this issue description and save to /spec using the name of this issue as the filename (with lower underscore case, starting with the 5 char padded issue number, e.g. 00001_issue_title.txt)
