I have added `__init__.py` in `maglodeve ` and `maglodeve/scripts` to turn
these directories to "modules".
As it, one can now install `maglodeve` using `pip install .` instead of `pip
install -e .`.

I have also added the URL of the gitlab project to the `setup.py` file and
`build` to `.gitignore`.

* Add a use case with data from the 2022 field trip in the `examples` directory.
The file has 3 columns separated by a comma.
* Add the description of the file and how to invert the data in the `Readme.md`
  file.
* Changed the way distances are displayed in the plot and the the value  of the
  position of the dyke returned after the inversion.
  Before, `pos` returned the relative position of the dyke with respect to the
  position of the maximum anomaly.
  Now everything is turned back to the distances indicated in the input file
  (distances set by the users).

I have changed the default column separator of the input file from `|` to `,` as
students will more likely use CSV file format.
I have modified the documentation to take this into account.

Add `.vscode` to `.gitignore`.

Add the equation (1) in Beiki & Pedersen (2012).

Update `LICENCE` and `Readme.md` and switch "red", "blue" and "nocolor" to uppercase in `ml_inversion.py`.
