Add parameter for maximum data

[jeff-hernandez]

Closes #213 by adding a maximum_data parameter to control when the label search should stop. You can use this parameter to generate year-to-date labels.

lt = lm.search(
  ...
  minimum_data='2021-01-01',
  maximum_data='2021-05-03',
  drop_empty=False,
)
