Add More Test Files

Add test files for CKF unit test. The existing data for KF unit test are also replaced because they had a bug from the older version of detray.

I also added a README.md file which contains commands used for data generation:

# Kalman filter validation
./bin/traccc_simulate_telescope --gen-vertex-xyz-std-mm=0:0:0 --gen-eta=0:0 --events=100 --gen-nparticles=100 --output_directory=detray_simulation/telescope/kf_validation/1_GeV_0_phi/
./bin/traccc_simulate_telescope --gen-vertex-xyz-std-mm=0:0:0 --gen-eta=0:0 --events=100 --gen-nparticles=100 --output_directory=detray_simulation/telescope/kf_validation/10_GeV_0_phi/
./bin/traccc_simulate_telescope --gen-vertex-xyz-std-mm=0:0:0 --gen-eta=0:0 --events=100 --gen-nparticles=100 --output_directory=detray_simulation/telescope/kf_validation/100_GeV_0_phi/

# Sparse Tracks
./bin/traccc_simulate_telescope --gen-vertex-xyz-std-mm=0:200:200 --gen-eta=0:0 --events=10000 --gen-nparticles=1 --output_directory=detray_simulation/telescope/sparse_tracks/single_tracks/
./bin/traccc_simulate_telescope --gen-vertex-xyz-std-mm=0:200:200 --gen-eta=0:0 --events=10000 --gen-nparticles=2 --output_directory=detray_simulation/telescope/sparse_tracks/double_tracks/
./bin/traccc_simulate_telescope --gen-vertex-xyz-std-mm=0:200:200 --gen-eta=0:0 --events=10000 --gen-nparticles=3 --output_directory=detray_simulation/telescope/sparse_tracks/triple_tracks/
./bin/traccc_simulate_telescope --gen-vertex-xyz-std-mm=0:200:200 --gen-eta=0:0 --events=10000 --gen-nparticles=10 --output_directory=detray_simulation/telescope/sparse_tracks/decade_tracks/

I didn't intend to change all tar files, but they ended up with slightly different size after running pack_files.sh @pagessin Do you know why this happens?

pack_files.sh packages all tar files. I'm guessing they contain the time or something? Can you simply manually not commit the files that you didn't intend to change?

OK I will do that. Please note that I will delete this branch for now and reopen the MR because git lfs is complaining with large data in my repository:

Locking support detected on remote "beomki". Consider enabling it with:
  $ git config lfs.https://gitlab.cern.ch/beyeo/traccc-data.git/info/lfs.locksverify true

Yeah I guess that's another problem: we might be hitting the storage limit if we're pushing updates. Somehow the repo is at 7.6GB total now, which I didn't expect.
