Merge pull request #1080 from CEED/ade/riemann-bcs

HLL Flux for Riemann BCs

examples/fluids: remove stray ceed/types.h (breaking GPU)

doc(fluids): Correct grammar in CLI descriptions

fluids: Add missing license header to stab_types.h

fluids: Move freestream bc setup to function

- This will allow it to be called from other problems more easily (ie.
for the Blasius problem)
