EnergyPlus-Modelica coupling

Issues are at https://github.com/lbl-srg/modelica-buildings/issues?q=is%3Aissue+is%3Aopen+label%3Aspawn

Next, work on

• Spawn FMUs are not yet self contained, https://github.com/lbl-srg/modelica-buildings/issues/2054 Should spawn.exe call be replaced by a call to a library function, with spawn.exe a wrapper for debugging? Michael to write up a specification for the implementation.
• Buildings library to report last E+ fatal error, https://github.com/lbl-srg/modelica-buildings/issues/2521

• [For FY21, Q2] Kyle to fix schedule: https://github.com/lbl-srg/modelica-buildings/issues/2000

  (Kyle either fixes it, or proposes new wording for https://lbl-srg.github.io/soep/softwareArchitecture.html#sending-input-to-energyplus)

• [For FY21, Q2] Kyle to look into numerical instability (walls may be initialized to wrong temperature). See for example Experimental/EnergyPlus/Examples/VAVReheatRefBldgSmallOffice/FloorOpenLoop. The temperature in the attic should not raise in the first hour. (Pending since Nov. 2019)
• Remove warnings issued by EnergyPlus, https://github.com/lbl-srg/modelica-buildings/issues/2220
• Support negative start time in EnergyPlus, https://github.com/lbl-srg/modelica-buildings/issues/1938

Plan for Spawn 0.x release by end of September, with Buildings Library 8.0.1 release (that includes bug fix for QLat_flow as in https://github.com/lbl-srg/modelica-buildings/issues/2602).

Other items
