[ScottBailey]

Changes

Changes:

• Update version from 1.5.1 to 1.9.1.
• mxnet moved it's 3rdparty libs from source into git submodules. We
  work around this by getting the archive commits from github.
• Ensure a modern compiler standard (c++14) is selected via patching.

We might need to get the package to build on osx-64 and osx-arm64

1.5.1 still builds (see #14), so this is not a problem on the builder.

Here's a PR for testing hacks: #12

[katietz]
