Network::run() should take void* (or byte*) instead of float*

[primenumber]

We want to take uint8_t, uint16_t or something else typed buffer for performance, memory usage optimization. Furthermore, we may want to take multiple input/output, it can be mixed-typed buffers. But current Network::run assumes input/output buffer are float-typed buffer. We should take only pointer of buffers.

network_run in network_c_interface should be fixed, too.
