5.0.0-alpha-20201224

This is a new pre-release of Tesseract 5.0.0.

It is considered to be production ready for end users, but nevertheless not stable because more incompatible API changes are planned.

• improved performance (also on ARM / ARM64)
• improved unit tests
• many fixes
• faster flat build with automake
• support for latest macOS (including new M1 processor)
