Fmpy

- `FIXED` Fix fmi3Functions.h for compile_platform_binary()
- `FIXED` Fix serialization in write_csv() (138)
- `FIXED` Check for existing documentation/licenses in add_remoting() (126)
- `FIXED` Fix function names in RPC calls (125)
- `CHANGED` Require pathlib only for Python version < 3.4
- `NEW` Update FMI 3 API to a51b173
- `NEW` Use defaultExperiment.tolerance as default in GUI (133)
- `NEW` Add "Tools" menu to GUI (124)
- `NEW` Make build configuration adjustable in build_remoting.py

- `FIXED` fmi2SetupExperiment() is now called again in FMI 2.0 for Co-Simulation
- `FIXED` The working directory for the remoting server is now set to binaries/win32
- `FIXED` ssp.simulation.set_value() has been fixed for Integer and Enumeration variables
- `NEW` A license file is now added to documentation/licenses when adding the remoting binaries to an FMU
- `NEW` A stop_time parameter has been added to ssp.instantiate_fmu()
- `CHANGED` The license has been changed to 2-clause BSD

**NOTE**: This release is currently not available on [conda-forge](https://anaconda.org/conda-forge/fmpy) because of [a bug in conda-build](https://github.com/conda/conda-build/issues/3929).

- `FIXED` A list is now passed to np.stack() instead of an iterable and Iterable is now imported from collections.abc to avoid FutureWarnings.
- `FIXED` Argument checksum of function fmpy.util.download_file() can now be upper case.
- `FIXED` Start and stop time are now passed to initialize() in FMI 1.0.
- `FIXED` Variadic arguments in log messages are now processed.
- `NEW` The model.png is now displayed on the "Model Info" page of the GUI.
- `NEW` 32-bit FMUs can now be simulated in a 64-bit Python environment on Windows.
Existing 32-bit FMUs can also be retro-fitted using the function fmpy.util.add_remoting(),
the CLI (fmpy add-remoting ...) and the GUI (Help > Add 32-bit Remoting).
- `NEW` The FMI headers and schema have been updated to version 2.0.1 and 3.0-alpha.3 respectively.
- `NEW` The function instantiate_fmu() allows the instantiation and re-use of an FMU independent of the FMI version and type to reduce CPU time.
See `examples/efficient_loops.py` for an example.
- `REMOVED` The parameter `use_source_code` has been removed form `simulate_fmu()` (use `fmpy.util.compile_platform_binary()` instead)

- `NEW` "Clear Plots" action has been added to the context menu
- `IMPROVED` single quotes are now removed from name segments in the tree view
- `IMPROVED` a RuntimeError is raised when an errors occurs in CVode
- `IMPROVED` exceptions are raised for undefined declaredType, illegal combinations of causality and variability, and missing shared libraries
- `IMPROVED` communicationPoint is now calculated as n_steps * step_size to avoid accumulation of numerical errors

This release re-adds the pre-compiled SUNDIALS libraries and has no functional changes w.r.t. v0.2.15.

- `FIXED` validation of structured variable names with apostrophes
- `FIXED` dimensions of variables in FMI 3
- `NEW` validation of "flat" variable names
- `UPDATED` FMI 3 schema files

- `IMPROVED` NULL pointers are now ignored in freeMemory()
- `IMPROVED` frequently used utility functions are now imported to fmpy module
- `IMPROVED` parameter_variation adapted to new Dask versions
