Add BCI Competition III - Dataset IVa (Berlin, 100z)

[griffinkeeler]

Summary

I would like to contribute a new dataset class for BCI Competition III - Dataset IVa (Berlin, 100z).

Dataset Details

• Subjects: 5
• Channels: 118
• Classes: right hand, feet
• Trial duration: 3.5s
• Total trials: 1400
• Format: MATLAB .mat files in a ZIP (EEG + labels)

Implementation

• New dataset class: BCICIII_IVa in moabb/datasets/bcic.py
• Compatable with MotorImagery paradigm -> CSP -> LDA
• Downloader uses dl.data_dl from the existing MOABB infrastructure

Questions

• Should the dataset be placed in a new bcic.py or should it be added to the existing bnci.py?
• Is BCICIII_IVa a good class name?

Don't we already have this dataset? The name should follow the BNCI pattern. The proposal name is not good.

If we don't have the dataset, the proposal is super welcome @griffinkeeler :)
