[GoPdfSuit] Add support for advanced mathematical rendering

Thank you for the amazing support; the repository now sits at 460+ **stars**. Introducing v5.0.0. This major release focuses on critical performance optimizations, reducing PDF generation time from 40ms to below 8ms. This update includes detailed performance benchmarks, sample data with comprehensive examples, and the corresponding generated files for verification, along with the typst syntax support for GoPDFSuit for basic maths formula's generation. **Performance Optimization Report** Benchmarks were conducted in a local development environment (WSL2, Intel i7-13700HX) to compare GoPdfSuit and GoPDFLib against industry standards, specifically testing against the workload mix popularized by Zerodha. **Key Results:** * **Throughput:** Achieved a peak throughput of 1913.13 ops/sec for GoPDFLib, significantly surpassing the 1000 ops/sec baseline derived from reported industry scales (1.5M PDFs in 25 minutes). * **Latency:** Reduced serial rendering time to as low as 2.48 ms for GoPDFLib and 2.87 ms for GoPDFSuit. * **Workload Mix Performance:** Validated using an 80/15/5 distribution (Retail/Active/HFT), ensuring efficiency across simple contract notes and complex, multi-page financial reports. * **Resource Efficiency:** In-memory processing with zero external dependencies. Image caching optimizations show a performance jump from 700 ops/sec to over 1500 ops/sec when enabled (gopdflib), while for gopdfsuit (gin api) it's around 300-500 ops/sec. * **Scalability:** Maintained stable performance across 48 concurrent workers with a controlled memory footprint. The results demonstrate that the engine is capable of crushing existing benchmarks on a single node in a development environment. The architecture is designed to maintain these results in production when deployed on similar hardware. **Existing and New Features:** * **JSON Template-based PDF generation** with automatic page breaks. * **Digital signatures (PKCS#7)** with X.509 certificate chains. * **PDF encryption** with password protection and granular permissions. * **Bookmarks, internal links, and named destinations.** * **PDF/A-4 and PDF/UA-2 compliance** for archival and accessibility standards. * **PDF merging** with a drag-and-drop interface. * **AcroForm and XFDF form filling.** * **HTML to PDF and Image conversion.** * **Typst syntax support** for mathematical rendering **(New)**. * **Secure PDF redaction** via text-search and coordinate mapping **(New)**. GoPdfSuit remains an open-source, FOSS project under the MIT license. It is built for high-compliance industries such as fintech, healthcare, and government, offering potential cost savings of up to $4000 compared to commercial alternatives. If you find this project useful, a **Star** on GitHub is much appreciated. Last time from community we got feature request for the maths support and the redaction while the maths support is somewhat basic, the redaction seems to be better than the Epstein PDF files itself :3 I am happy to answer any questions or if you have any feature request let me know. **GitHub:** [https://github.com/chinmay-sawant/gopdfsuit](https://github.com/chinmay-sawant/gopdfsuit) **Documentation:** [https://chinmay-sawant.github.io/gopdfsuit/](https://chinmay-sawant.github.io/gopdfsuit/) **YT Demo:** [**https://youtu.be/PAyuag\_xPRQ**](https://youtu.be/PAyuag_xPRQ)
