How to create custom op with fp16 input

[CapJunkrat]

Describe the issue

I tried to use custom op functionality to create a custom op (what it does is exactly the same with QuantizeLinear) with fp16 type input, but when I try to inference it, onnxruntime throws error:

onnxruntime.capi.onnxruntime_pybind11_state.RuntimeException: [ONNXRuntimeError] : 6 : RUNTIME_EXCEPTION : Non-zero status code returned while running HzQuantize node. Name:'HzQuantize_0' Status Message: unknow input type

I checked the function that throws the error, it is "Variadic" initialization function in file "onnxruntime_lite_custom_op.h" , and Float16_t and BFloat16 types are not in the "switch (type)" command, and "ORT_CXX_API_THROW("unknow input type", ORT_RUNTIME_EXCEPTION);" is given from the default switch branch.

Is this done on purpose or just fp16 function not supported yet? Is there a way to give custom op fp16 input type?
