Provide new chunking strategies in localdocs

[manyoso]

Currently we do a character/word based chunking that is very simple. We should enhance our chunking strategies to possibly include:

• Recursive Character Chunking
• Token Based Chunking
• Document Specific Chunking (HTML, MD, Python, CPP, etc)
• Semantic Chunking
