Add Digital typhoon dataset (microsoft#1748)

* analysis task dataset * implement sequence sampling * add outline datamodule * add datamodule with two way splitting capabilities * add plotting function * download and verify * add unit tests but they fail * fix tests * fix style * trainer testing yaml * test split logic * fix tests * fix tests2 * found bug * try to fix mypy * h5py error docs * fix docs * fix one mypy error * mypy on test file * fix coverage * fix tests for trainers * fix mypy * try typed dict * try to fix docs * fix pytest * linters * suggested changes and normalization procedure * regression target normalization * update dataset splitting * fix test * quotes * strings * ruff * quotes * ruff format on all * docs * lazy import * h5py * h5py datamodule * typo * tests * review * pass tests * fix tests * list -> tuple * mypy fix * rename * tests * Remove Analysis * min pandas 2.2.0 * resolve tests --------- Co-authored-by: Adam J.
