Bug: pformat_dict not imported from utilities

[radlfabs]

from flexcv import CrossValidation
from flexcv.synthesizer import generate_regression
X, y, groups, _ = generate_regression(12, 300, 10)
from flexcv.models import LinearModel

cv = CrossValidation()

performed = (
    cv
    .set_data(X, y, groups)
    .set_splits()
    .add_model(LinearModel)
    .perform()
    .get_results()
)

raises "NameError: name 'pformat_dict' is not defined".

Problem is here:

flexcv/flexcv/results_handling.py

Line 79 in e260729

return f"CrossValidationResults {pformat_dict(self)}"

We need to import pformat_dict from flexcv.utilities.
