Breaking Changes

1. MacOS binaries are now renamed from osx- to macos-
2. MacOS aarch64 binaries are now renamed, dropping the -apple-darwin suffix
   1. libpact_ffi-osx-aarch64-apple-darwin.a.gz to libpact_ffi-macos-aarch64.a.gz
3. Shasum embedded filenames have now changed to only include the filename, dropping the full path prefix, which would differ depending on the host machine building the binaries.
