bugfix(ev-cli): support array type in subscription

- the json array object has been casted to `nlohman::json::array` so
  far, instead of `std::vector<ItemType>` for subscription
- this commit introduces some code duplication, as it copies the
  handling from the `_gather_cmds` implementation -- this should be
  refactored
- NOTE: the array of enum handling has not been checked
