Integrate the data, metrics, and methods of the TimeSeAD library into TimeEval:

• Paper: https://ml.informatik.uni-kl.de/publications/2023/TimeSeAD.pdf
• Code: https://github.com/wagner-d/TimeSeAD

Changes:

• Adjusted SMD collection datasets with only 15 time series (create new collection SMD-TimeSeAD
• Adjusted Exathlon datasets (other value imputation, TS filtering) (create new collection Exathlon-TimeSeAD)
• New metric: adjustments of the RangePrecision and RangeRecall metrics by TatbulEtAl2018

  T_{Rec} and T_{Prec}. We propose new default parameters for T_{Rec} and a variation of T_{Prec} to address their flaws.

• New methods:
  • TCN-S2S-AE
  • TCN-S2S-P
  • GenAD
  • STGAT-MAD
  • AnomalyTransformer (existing issue Add AnomalyTrans TimeEval-algorithms#29)
  • SIS-VAE
  • TadGAN
  • THOC
  • NCAD
  • GRELEN
