ROCArrays - Julia Arrays for Radeon/AMD GPUs

ROCArrays is currently an experimental package, and many things are broken or not implemented.

ROCArrays is a cousin package to CuArrays, but instead provides array operations for AMD GPUs running on the ROCm stack. We strive to match CuArray's API to make it easy for users to use either stack with minimal code changes.

ROCArrays builds on the excellent work done by Tim Besard and contributors to CuArrays.jl, and would not exist in a working state without their hard work.
