Define team model

The team strength lookup has three components: an input, an embedding layer, and a flatten layer that creates the output.

If you wrap these three layers in a model with an input and output, you can re-use that stack of three layers at multiple places.

Note again that the weights for all three layers will be shared everywhere we use them.

Create a 1D input layer for the team ID (which will be an integer). Be sure to set the correct input shape!
Pass this input to the team strength lookup layer you created previously.
Flatten the output of the team strength lookup.
Create a model that uses the 1D input as input and flattened team strength as output.
