Quantized saved_model size increased.

[JuHyung-Son]

I followed colab tutorial and noticed that quantized mode size is increased after converting.
Is this an expected result?? I expected the quantized model size would be decreased.

I checked this PR 30789, but it doesn't work as expected.

I have same problem. I'm quantizing a model to reduce the size, not to make it larger :/
