Broken functionality because of missing dependency should be shown in GUI

And not only in an exception. For example, if one tried to export to Excel without xlwings installed (see larray-project/larray#1128), we raise an helpful exception but a user using the GUI would never see it.

In fact, the user-visible error message was already foreseen and this is apparently fixed in the devel branch already without changing the "outer function" with the error message code 😉 . The problem is that the exception raised (Exception) was not the same as the Exception caught (ImportError):

Traceback (most recent call last):
  File "C:\soft\Miniconda3x64\envs\dev313\Lib\site-packages\larray_editor\arraywidget.py", line 1097, in to_excel
    self.data_adapter.to_excel(raw_data, axes_names, vlabels, hlabels)
    ~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\soft\Miniconda3x64\envs\dev313\Lib\site-packages\larray_editor\arrayadapter.py", line 373, in to_excel
    wb = la.open_excel()
  File "C:\soft\Miniconda3x64\envs\dev313\Lib\site-packages\larray\inout\xw_excel.py", line 643, in open_excel
    raise Exception("open_excel() is not available because xlwings is not installed")
Exception: open_excel() is not available because xlwings is not installed
