heyoka 7.8.0

[bluescarni]

This latest heyoka release focuses on implementing thread safety for compiled functions and related classes. Specifically, it is now safe to use the same cfunc object concurrently from different threads of execution. The same holds for the SGP4 propagators.

As a consequence of the thread-safety changes, cfunc is now an immutable lightweight class with constant-time noexcept copy semantics.

As a further small feature addition, it is now possible to pass the optional batch_parallel boolean flag to the call operator of a cfunc to explicitly enable/disable multithreaded parallelism during batched evaluations.

The full changelog, as usual, is available here:
