Test Record

model infer time unit is ms;
Sort by performance, compare priority: mbnet128 > vww96 > cifar > mnist

Note1: arduino run another smaller mnist model due to limited memory
Note2: all model record fastest model type's infer time, for example, C906 use FP16 result. Note3: XXX means impossible run this model on that chip
