simulations (#1761)
* Update copyright notices
* allow specification of boundary potentials at runtime when using Dirichlet boundary conditions in the electrostatic solver (labframe)
* added parsing to boundary potentials specified at runtime to allow time dependence through a mathematical expression with t (time)
* updated to picmistandard 0.0.14 in order to set the electrostatic solver convergence threshold
* update docs
* various changes requested during PR review
* fixed issue causing old tests to break and added a new test for time varying boundary potentials
* possibly a fix for the failed time varying boundary condition test
* changed permission on the analysis file for the time varying BCs test
* switched to using yt for data analysis since h5py is not available
* made changes compatible with PR#1730; changed potential boundary setting routine to use the ParallelFor construct and set all boundaries in a single call
* fixed typo in computePhiRZ
* updated docs and fixed other minor typos
* fixed bug in returning from loop over dimensions when setting boundary potentials rather than continuing
* changed to setting potentials on domain boundaries rather than tilebox boundaries and changed picmi.py to accept boundary potentials
* now using domain.surroundingNodes() to get the proper boundary cells for the physical domain
* fixed typo in variable name specifying z-boundary potential
* changed boundary value parameter for Dirichlet BC to boundary.field_lo/hi and changed setPhiBC() to only loop over the grid points when a boundary value has changed
* switched specifying potential boundary values though individual inputs of the form boundary.potential_lo/hi_x/y/z and incorporated the new BC formalism through FieldBoundaryType::Periodic and FieldBoundaryType::PEC rather than Geom(0).isPeriodic(idim)
* removed incorrect check of whether the potential boundary values are already correct, also had to change the input to test space_charge_initialization_2d to comply with the new boundary condition input parameters and finally changed permissions to analysis_fields.py file for the embedded boundary test since it was failing
* remove line from WarpX-tests.ini that was incorrectly added during upstream merge
* changed input file for relativistic space charge initialization to new boundary condition specification
* fixed outdated comment and updated documentation to reflect that the Dirichlet BCs can also be specified when using the relativistic electrostatic field solver
* moved call to get domain boundaries inside the loop over levels
* cleaned up the code some by using domain.smallEnd and domain.bigEnd rather than lbound and ubound
* added check that a box contains boundary cells before launching a loop over that box cells to set the boundary conditions
