MaixPy support new nncase & Kmodel V4 Now~

The problem described above occur only if I use NNCase v0.2.0 Beta3, if I use NNCase v0.2.0 Beta2 the kmodel obtained is OK and the program run but is slow at 0.9 fps.

I see that in Beta3 there are optimization (also for matmul) I hope that if I will be able to compile with it (or maybe with a forthcoming Beta4) I obtain a greater fps.

@Zepan do you think that what I described in my two last post could be related to some bug in NNCase v0.2.0 Beta3?



@zepan could you provide the source code for this version of the MaixPy sofware?
