Construct a "fast" ELECTRA tokenizer (backed by HuggingFace's *tokenizers* library).
[`ElectraTokenizerFast`] is identical to [`BertTokenizerFast`] and runs end-to-end tokenization: punctuation
splitting and wordpiece.
Refer to superclass [`BertTokenizerFast`] for usage examples and documentation concerning parameters.
