Add example with data other than dykes (e.g. fracture trace data)

[nialov]

Just to preface: use of this specific data is just a suggestion, feel free to use any other source! I do believe, however, that adding some (small) example(s) with data other than dyke data is needed to make evident the general usability of the software. No complex analysis is required for this purpose, just show how it is loaded (in csv form or with geopandas) and a simple analysis with e.g. the Cartesian space - Hough Transform space plot.

My data suggestions

I have personally been involved with gathering fracture trace data and some of our data is publicly available:

• https://zenodo.org/records/7077846

The data consists of ESRI Shapefile data that can be loaded with geopandas (See #20) or with QGIS and transformed to csv to work with the current API.

• https://zenodo.org/records/7919843

This dataset is contains code and data. Fracture trace data is in data/trace_data/traces/20m/ folder in geojson data type.

You can freely add individual files/parts of files to this repository as the datasets are openly and freely licensed. Just add a mention and link to Zenodo or the DOI found on the Zenodo pages in e.g. the README.md or some other suitable place.
