#Centipede Corpus seeder: More accurate logged count of non-empty features

`ReadShard()` passes two types of empty features into the callback:
1. Truly empty, when the features file doesn't contain features for the current input and the client needs to recompute them.
2. A single element `FeatureVec{feature_domains::kNoFeature}`, when the features file contains an empty record for the current input, i.e. the input genuinely didn't trigger any features, and there is no need to recompute them.
