* **NEW:** Introducing **CamemBertForSequenceClassification** annotator in Spark NLP 🚀. `CamemBertForSequenceClassification` can load CamemBERT Models with sequence classification/regression head on top (a linear layer on top of the pooled output) e.g. for multi-class document classification tasks. This annotator is compatible with all the models trained/fine-tuned by using `CamembertForSequenceClassification` for PyTorch or `TFCamembertForSequenceClassification` for TensorFlow in HuggingFace 🤗
* **NEW:** Add `AnnotatorType` validation in Spark NLP `LightPipeline`. Currently, a misconfiguration of `inputCols` in an annotator in a pipeline raises an exception when using `transform` method, but in `LightPipeline` it only outputs empty values. This behavior can confuse users, this change introduces a validation that will raise an exception now in `LightPipeline` too.
* Add outputAnnotatorType for all annotators in Python
* Add inputAnnotatorTypes and outputAnnotatorType requirement validation for all subclasses derived from `AnnotatorApproach` and `AnnotatorModel`
* Adding AnnotatorType validation in `LightPipeline`

* Use the new withIncludeScala in assemblyOption instead of value
----------------
Bug Fixes
----------------
* Fix an issue with the `BigTextMatcher` Annotator, where it would not match entities with overlapping definitions. For Example, if both `lung` and `lung cancer` are defined, `lung` would not be matched in a given text. This was due to an abstraction error of one of the subclasses of the `BigTextMatcher` during construction of the underlying data structure
* Fix indexing issue for `RegexTokenizer` annotator. If the document was split into sentences, the index of the sentence inside the document was not taken into consideration for the indexes of the tokens. This would lead to further issues down the pipeline, where tokens would be filtered while unpacking them for other Annotators

New Features & Enhancements
----------------
* **NEW:** Introducing **Wav2Vec2ForCTC** annotator in Spark NLP 🚀. `Wav2Vec2ForCTC` can load `Wav2Vec2` models for the Automatic Speech Recognition (ASR) task. Wav2Vec2 is a multi-modal model, that combines speech and text. It's the first multi-modal model of its kind we welcome in Spark NLP. This annotator is compatible with all the models trained/fine-tuned by using `Wav2Vec2ForCTC` for **PyTorch** or `TFWav2Vec2ForCTC` for **TensorFlow** models in HuggingFace 🤗 (https://github.com/JohnSnowLabs/spark-nlp/pull/12767)

TAPAS is a BERT-based model specifically designed (and pre-trained) for answering questions about tabular data. This annotator is compatible with all the models trained/fine-tuned by using `TapasForQuestionAnswering` for **PyTorch** or `TFTapasForQuestionAnswering` for **TensorFlow** models in HuggingFace 🤗

(https://github.com/JohnSnowLabs/spark-nlp/pull/12752)
* Implementing `setTestDataset` to evaluate metrics on an external dataset during training of Text Classifiers in Spark NLP. This feature is similar to NerDLApproach where metrics are calculated on each Epoch and have been added to the following multi-class/multi-label text classifier annotators: `ClassifierDLApproach`, `SentimentDLApproach`, and `MultiClassifierDLApproach` (https://github.com/JohnSnowLabs/spark-nlp/pull/12796)
* Refactoring and improving `EntityRuler` annotator inference to up to 24x faster especially when used with a long list of labels/entities.

However, a bug was introduced in sentence indices which when it is combined with SentenceEmbeddings for Text Classifications tasks (ClassifierDLApproach, SentimentDLApproach, and ClassifierDLApproach) resulted in low accuracy: AlbertEmbeddings, CamemBertEmbeddings, DeBertaEmbeddings, DistilBertEmbeddings, LongformerEmbeddings, RoBertaEmbeddings, XlmRoBertaEmbeddings, and XlnetEmbeddings (https://github.com/JohnSnowLabs/spark-nlp/pull/12641)
* Add support for a list of questions and context in LightPipeline. Previously, only one context and question at a time were supported in LightPipeline for Question Answering annotators.
