Is your feature request related to a problem? Please describe.
A new API feature allows wild cards.

Describe the solution you'd like
In any case where we are filtering by object_value, like object--support--pole or for traffic signs regulatory--stop--g1, we can also send to the API a filter like object--*--* to get all objects or object--sign--* to get all sign map features (store, advertisement, etc).

Describe alternatives you've considered
None

Additional context
This only works on API requests with there is an object_values= parameter, so may not be relevant to the SDK for now, though we could do the same filter style when requesting from the tiles, to make sure it behaves the same using the wild cards.
