Add jquick-excel: declarative XML DSL for Excel import/export

[paohaijiao]

Adds Jquick Excel to the Excel section.

What makes it different from other Excel libraries is the XML DSL approach. Most existing solutions either force you to write tons of POI code or rely on annotations that require recompilation when rules change. This one puts all the mapping, validation rules, formulas, and styling into XML files, so you can tweak the import/export logic without touching Java code.

It supports 20+ validation rules (email, mobile, regex, range, dictionary lookup), 50+ formulas, and 10 chart types. The project is actively maintained with several releases out already, and the documentation is available in both English and Chinese.

Not a commercial project, just a solid open-source tool that fills a gap in the Excel processing space.
