If the build is based on imported instrument data, use imported protocols

This could be something like:

```perl
my @instrument_data = $build->instrument_data(subclass_name => 'Genome::InstrumentData::Imported');
return scalar(@instrument_data)? 1: 0;
```

Alternatively, I might replace `$id->class eq 'Genome::InstrumentData::Imported'` with `$id->isa('Genome::InstrumentData::Imported')`.
