Support for 16 bit activations in ExpandDims operation.
Hi @miaout17, can you please take a look? Thanks. Hi @robertkamara,

It looks like this issue appears to have been resolved since PR [#2589](https://github.com/tensorflow/tflite-micro/pull/2589) was already merged into TFLite-micro repo.

Thank You

The task is to add support for 16-bit activations and 8-bit weights in ExpandDims operation. Currently, only float32 and int8_t types are supported:
