Announce: passagemath 10.6.1.rc2 - modularized pip-installable fork of Sage

[Matthias Koeppe]

https://github.com/passagemath/passagemath/releases/tag/passagemath-10.6.1.rc2

First binary wheels for native Windows

Started porting to Windows x86_64. Libs are built on mingw, then linked using native build tools in cibuildwheel.
Due to passagemath's modularized design, porting can be done separately 1 dependency at a time, producing immediately usable wheels, to be published to PyPI.

As of passagemath-10.6.1.rc2, binary wheels for passagemath-objects and passagemath-categories are available.
