Update run script for local builds

[gigony]

• Update run script to download GDS from public package (cufile.h is needed to build it locally)
  • Update CMakeLists.txt accordingly
  • GDS is still disabled (need to use GDS Conda package and verify it before enabling GDS)
• Update CUDA EULA (which include libcufile)
• Add dependency to yasm which is needed for building libjpeg-turbo
• Clear CMakeCathe.txt and existing .so files to build with the updated options
• Minor code change (unnecessarily std::move which degrade performance).
• Add changelog for v0.18.3 and update the release date of v0.19.0 to 4/19/2021

Verified with a fresh system that https://github.com/rapidsai/cucim/blob/branch-0.20/CONTRIBUTING.md#script-to-build-cucim-from-source is working. (Previously it didn't work due to yasm dependency).

Hi @raydouglass

Since we didn't tag v0.19.0 yet and VERSION files in branch-0.20 are still referring to 0.19.0, would it make sense to fast-forward branch-0.19 branch to branch-0.20 instead of creating a PR with the same commits to branch-0.19?

If branch-0.19 is not available for fast-forwarding, I can create a PR with the duplicate commits in branch-0.20 for branch-0.19.

I see some build error because python build is using the existing libcucim conda package but libcucim code in C++ is also changed in the PR.
: https://gpuci.gpuopenanalytics.com/job/rapidsai/job/gpuci-v0.20/job/cucim/job/prb/job/cucim-cpu-python-build/CUDA=11.0,PYTHON=3.7/17/console line 704

Wonder if I need to push PRs for libcucim(core lib code) and cucim (pybind11&python code) separately.

It seems that it always using libcucim from nightly build

https://gpuci.gpuopenanalytics.com/job/rapidsai/job/gpuci-v0.20/job/cucim/job/prb/job/cucim-cpu-python-build/CUDA=11.0,PYTHON=3.7/18/console

18:08:35     libcucim:         0.19.0a210416-cuda11.0_g6cfdbfb_9 rapidsai-nightly  

@ajschmidt8 Do you have any idea on that? How could we handle the situation?

[gigony]

I found that libcucim's built package is available at ${WORKSPACE}/ci/artifacts/cucim/cpu/.conda-bld when cucim is built so I updated build.sh for cpu cucim build through cd3ae09, to use cpu libcucim build.
This approach was already made in GPU build (https://github.com/rapidsai/cucim/blob/branch-0.20/ci/gpu/build.sh#L61).

This PR is passing now.

@quasiben, please help review the change.
This change also requires an approval from @jakirkham (rapidsai/cucim-cpp-codeowners) so I don't know how to merge it without @jakirkham's help.

Thanks @gigony I'll port these changes back to 0.19 after being merged
