adding onnxruntime to atlasexternals/1.0
This is my attempt to introduce onnxruntime into atlas/atlasexternals:1.0 so it can be used in athena/21.2 I was able to compile it locally by doing following
setupATLAS
asetup none,gcc62,cmakesetup --cmakeversion=3.14.7
cmake ../atlasexternals/Projects/AthenaExternals
make Package_onnxruntime
I am keeping it WIP for sometime till I am able to run example algorithm in athena/21.2. Adding @akraszna , @dguest, @afarbin for comments.
