MaartenGr/BERTopic: v0.9.2

A release focused on algorithmic optimization and fixing several issues:

Highlights:

• Update the non-multilingual paraphrase- models to the all- models due to improved performance
• Reduce necessary RAM in c-TF-IDF top 30 word extraction

Fixes:

• Fix topic mapping
  • When reducing the number of topics, these need to be mapped to the correct input/output which had some issues in the previous version
  • A new class was created as a way to track these mappings regardless of how many times they were executed
  • In other words, you can iteratively reduce the number of topics after training the model without the need to continuously train the model
• Fix typo in embeddings page (#200)
• Fix link in README (#233)
• Fix documentation .visualize_term_rank() (#253)
• Fix getting correct representative docs (#258)
• Update memory FAQ with HDBSCAN pr
