train-test-splits for `datasets`

[David Berenstein]

Training models is fun, data transformations are not, so why not do them in the background.

MVP

from argilla_plugins.datasets import train_test_split

train_test_split(name="dataset_from")
train_test_split.start()

Stretch
filtering variables like query or train_size test_size, val_size could be added.
