v5.0.0

Update some links

tesseract 4.1

tesseract 4.1

• Fix memory leak in ocr_data()
• Windows / MacOS: update to libtesseract 4.1.0. This re-enables
  the whitelist/blacklist options that were missing in Tesseract 4.0

tesseract 4.0

tesseract 4.0

• Windows, MacOS: Upgrade to upstream Tesseract 4.0! Completely new OCR engine.
• Tesseract 4 has a new training data format. On Windows / MacOS you need to
  re-download your language data with tesseract_download(). The package uses
  separate directories for storing Tesseract 3 vs 4 data so they shouldn't get
  mixed up (hopefully).
• Drop hard-dependency on tibble (only load if available)
