https://igel.readthedocs.io/en/latest/_sources/readme.rst.txt includes a link to the assets/igel-help.gif, but that path is broken on readthedocs.

readme.rst is included as ../readme.rst in the sphinx build.
The gifs are in asses/igel-help.gif

The sphinx build needs to point to the asset directory, absolutely:

.. image:: /assets/igel-help.gif

I haven't made a patch, because I haven't

Is your feature request related to a problem? Please describe.
Change split values from all caps to lower case.
This makes file/directory naming more consistent with the split.

Describe the solution you'd like
TRAIN -> train
VALIDATION -> validation
TEST -> test

Describe alternatives you've considered

1. No change

• There's a bit of skew when it comes to mapping split val

This will help prevent code break when some user has an old dependency.

Considerations: Will need to check the lowest version to minimise the unnecessary updates
