Configuration options are:
- casters: a map of VarDumper Caster objects to use instead of the default casters.
- additional_casters: a map of VarDumper Caster objects to use in addition to the default
casters.
- max_items: maximum number of items to clone beyond the minimum depth.
- max_string: maximum string size
- min_depth: minimum tree depth to clone before counting items against the max_items limit.
(Requires Symfony 3.4; ignored on older versions.)
