Add numbin as another serialization library

[kemingy]

Hi, I'm the author of numbin (An efficient binary serialization format for numpy data.) I just found this repo and I wonder if you will accept numbin as another serialization library.

Check the benchmark here.

BTW, I don't know there is a library called msgpack-numpy before I develop numbin. After explore the source code, I think numbin would provide better performance and flexibility.

Thanks for the pointer! To a large extent srsly is developed for the formats we're using for Explosion packages/projects and my initial feeling is that we're unlikely to replace msgpack-numpy with another option unless there are large advantages because it could be complicated to handle a lot of the existing saved data.

We do occasionally run into the size limits for items saved with msgpack, but it looks like this would be the same for numbin?

That depends. Numbin doesn't require msgpack if your data is just NumPy array. It's only required when you have the mixed data type.

I'm not sure about the msgpack size limitation. Will take a look.
