text: Title: Conda enviroments at customized locations
  Body: When the VBA code tries to load the XLWings dll and there is a Conda Env informed, it tries to load the DLL from:
  
  ```
  {Conda Path}\envs\{Conda Env}\xlwings...dll
  ```
  
  In Windows, `Conda Path` usually is something like `C:\ProgramData\Miniconda3` and the default path for the conda environments is `C:\ProgramData\Miniconda3\envs\`, and so everything works.
  
  But when we customize the path where the conda enviroments are created (with `conda config -add envs_dirs <path>`), it breaks, because now the DLL is at `<path>\{Conda Env}\xlwings...dll`.
