Add streamxl — Rust-powered streaming XLSX reader for Python

[Mullassery]

streamxl

https://github.com/Mullassery/StreamXL

A Python library that reads .xlsx files row-by-row using a Rust engine (PyO3 + quick-xml), without loading the entire file into memory.

Why it belongs in the MS Office section:

• Direct alternative to openpyxl for reading large Excel files
• 4–5× faster than openpyxl, uses ~13× less memory at 250k rows
• Streams row-by-row — API is a single iterator: for row in streamxl.read("file.xlsx")
• Ships as a pip/uv wheel: pip install streamxl
