Re-implement process_author_roles in Rust

It seems to be about twice as fast as the Ruby implementation:

```
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") { process_author_roles(record) }
  x.report("rust version") { BibdataRs::Marc.author_roles(marc_breaker) }
  x.compare!
end
