~ ($HOME) in path not supported by PyStemmusScope

[BSchilperoort]

I tried to use the ~ character in the file paths when setting up the PyStemmusScope configuration, however, this does not seem to be supported. Instead I have to use the (full) absolute path.

Would we want to support this? pathlib's .expanduser() will retrieve the home directory from ~.

>>> pth = pathlib.Path('~/STEMMUS_SCOPE_data/model_parameters/vegetation_property/')
>>> pth.expanduser()
PosixPath('/home/bart/STEMMUS_SCOPE_data/model_parameters/vegetation_property')

yes, we can refactor read_config to use utils.to_absolute_path.
