Pixi package definitions

Pixi package definitions

Pixi package definitions have been added for different kinds of from-source builds of NumPy. These can be used in downstream Pixi workspaces via the pixi-build feature.

Definitions for both default and AddressSanitizer-instrumented (asan) builds are available in the source code under the pixi-packages/ directory.

linux-64 and osx-arm64 platforms are supported.
