aerynOS New Package Pull Request

Summary

Testing Performed

• I have tested the package and can confirm that just build completes successfully, the package installs via moss and that the application functions as expected
• No obvious security or stability concerns or any regressions observed in testing
• The package was tested against the volatile stream

Additional testing notes:

I ran the tests provided by proj themselves in the recipe.
And then I ran my code as usual and was able to project points from the EPSG:3857 projection to the EPSG:4326 successfully.
