Release focusing on length adjustments. Much more dynamism and on-the-fly adaptation, both for query length and maximum document length!

• Remove hardcoded maximum length: it is now inferred from your base model's maximum position encodings. This enables support for longer-context ColBERT, such as Jina ColBERT
• Upstream changes to colbert-ai to allow any base model to be used, rather than pre-defined ones.
• Query length now adjusts dynamically, from 32 (hardcoded minimum) to your model's maximum context window for longer queries.
