SpiceyPy 7.0.0-alpha

[7.0.0-alpha] - 2025-08-29

Alpha Release of SpiceyPy with Cyice, Cython accelerated Spice

This is just for testing new build system/ci steps for publishing artifacts.
They should show up on testpypi, if not we may do a few more alpha releases...

Added

• Cython extension submodule Cyice for accelerated SpiceyPy
• Cyice includes wrappers for over 90 CSPICE functions, vectorized for majority of functions, shares kernel pool with spiceypy so new functions are drop-in replacements
• Cyice functions tested and benchmarked against spiceypy ctypes wrapper functions
• new cyice docs
• new required reading docs pages (#489)
• python 3.13 builds (#488) and native aarch64 runners (#490)

Fixed

• Various issues and typos in docs (#503) (#492) (#350) (#481) (#477)
• Various CI improvements (#484) (#479)

Changed

• Switched build system to scikit_build_core/cmake to simplify builds
• Pckcov returns “cover” arg (#504)
• URLs to naif are now versioned (#493)

Removed

• Get_spice.py, setup.cfg, setup.py, and related old build system
