SPARKNLP-962: UAEEmbeddings

[DevinTDHa]

Description

This PR adds an Annotator for UAE embeddings. For this, new pooling operations for word embeddings have been added.

Namely poooling by

1. Using a token at a specific index (such as the [CLS] token, or the last token)
2. Max pooling across the sequence dimension
3. [CLS] + Mean of the embeddings

These can be set with setPoolingStrategy for the annotator.

Additionally, it fixes a bug with serializing onnx models that do not have a .onnx_data file (b73dc0b). @prabod I think you worked on this part, could you review if the fix looks good? I provided a description in the commit message. Thanks!

How Has This Been Tested?

New tests and old tests are passing.

Hi @maziyarpanahi,

Yes, the fix should prevent the error in the notebook as well.
