Bug 30848: Add an ExpandCodedFields RecordProcessor filter

This patch introduces a RecordProcessor filter for MARC::Record objects
that replaces Koha codes with descriptions in the MARC::Record passed to the processor.

Target usage:

  my $biblio = Koha::Biblios->find(
      $biblio_id,
      { prefetch => [ metadata ] }
  );

  my $record = $biblio->metadata->record;

  my $processor = Koha::RecordProcessor->new(
    {
        filters => ('ExpandCodedFields'),
        options => {
            interface     => 'opac',
            frameworkcode => $biblio->frameworkcode
        }
    }
  );

  $processor->process( $record );
