Add other related rOpenSci packages to the README?

Would you mind adding (or receiving a PR) adding a "related packages" section to the README (and therefore pkgdown website)?

It could mention

• tesseract by @jeroen for more direct control of the OCR process.

• pdftools for extracting metadata and text from PDF files (therefore more specific to PDF, and without a Java dependency)

• tabulizer by @leeper and @tpaskhalis, Bindings for Tabula PDF Table Extractor Library, to extract tables, therefore not text, from PDF files.

• epubr by @leonawicz (about to be onboarded) which is more specific than rtika and therefore gives an user-friendlier output when parsing epub files.

I think it'd help people choose a package suitable to their needs. rtika is a powerful package for many formats, which I hope you don't think I'm forgetting. 😺

Thanks in advance!
