A static implementation of isinstance() - instead of comparing an object and a class, the object is compared to a
string, like 'pyiron.base.job.generic.GenericJob' or a list of strings.
Args:
obj: the object to check
obj_type (str/list): object type as string or a list of object types as string.
Returns:
bool: [True/False]
