Streaming features that support dot products among other operations.
DotFeatures support the following operations:
dot product between feature vectors:
\[r = {\bf x} \cdot {\bf x'}\]
dot product between feature vector and a dense vector \({\bf z}\):
\[r = {\bf x} \cdot {\bf z}\]
multiplication with a scalar \(\alpha\) and addition to a dense vector \({\bf z}\):
\[ {\bf z'} = \alpha {\bf x} + {\bf z} \]

Adds a subset of indices on top of the current subsets (possibly subset of subset). Every call causes a new active index vector to be stored. Added subsets can be removed one-by-one. If this is not needed, add_subset_in_place() should be used (does not store intermediate index vectors)

Sets/changes latest added subset. This allows to add multiple subsets with in-place memory requirements. They cannot be removed one-by-one afterwards, only the latest active can. If this is needed, use add_subset(). If no subset is active, this just adds.
