Rewrite cataloged_tdt in Rust

It is ever so slightly faster than Ruby:

```
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") { cataloged_tdt_impl(record) }
  x.report("rust") { BibdataRs::Marc.cataloged_date(marc_breaker) }
  x.compare!
end
```

```
