Re-write call number browse and display in Rust (#3012)

* Re-write call number browse and display in Rust

This is a performance improvement over the original ruby as
measured by this microbenchmark:

```
require 'benchmark/ips'
record = MARC::XMLReader.new('spec/fixtures/marc_to_solr/9939238033506421.mrx').first
marc_breaker = MarcBreaker.break(record)
Benchmark.ips do |x|
  x.report("ruby version") { browse_fields(record, marc_breaker:) }
  x.report("rust version") { BibdataRs::Marc.call_number_labels_for_display(marc_breaker) }
  x.compare!
end
```

...which outputs:

```
