Clean up services and command line applications

• Replace HazardCalc with code of Hazard2018
  • There is no longer a WUS/CEUS distinction
• Merge DisaggCalc, DisaggIml, and DisaggEpsilon
  • Return period disagg calculation in nshmp-lib is deprecated in favor of IML
  • Site file defines IMLs; these could be:
    • RTGMs
    • IMLs corresponding to a single return period
  • Arguments (in lib): Map<Imt, Double>, HazardModel, Optional<GroundMotions>
    • Ground motions could be supplied from static curves or a dynamic calculation
    • If empty, the dynamic hazard calculation would run
• Migrate disagg services to micronaut
• Remove site string options; consider removing in other calcs; site file only
• Check disagg PGV (have note that disagg needs calc-config w/o PGV)
