VUnit 4.1.0 breaks VHDL 2008 library settings for GHDL #594
Description
Since upgrading to VUnit 4.1.0, I've got problems using with GHDL.
For example, I add in my run.py
test_lib = vu.add_library("test_lib")
test_lib.add_source_files("tests/hdl/*.vhd")I get the following error when running run.py
File "/home/baumannt/devel/workspaceSigasi/vertical-lines-fpn/venv/lib/python3.8/site-packages/vunit/ui.py", line 838, in main
all_ok = self._main(post_run)

File "/home/baumannt/devel/workspaceSigasi/vertical-lines-fpn/venv/lib/python3.8/site-packages/vunit/ghdl_interface.py", line 157, in setup_library_mapping

RuntimeError: GHDL cannot handle mixed VHDL standards, found ['2008', VHDLStandard('2008')]
It seems that the default VHDL standard label isn't working anymore.
