8552534b61 Use u32 for struct and member variables in IWP, saturating to u32::MAX (yancy)
Pull request description:
Use u32 for struct and member variables in InputWeightPrediction (saturating to u32::MAX). To avoid panics during construction and while using auxiliary methods such as `total_size()`, support saturating operations.
