   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   
   What we are working on will use `filter` kernel. One feature we may need is 
to filter by providing indices. But currently the public API `filter` only 
accepts a boolean array.
   
   Internally, there is several `IterationStrategy`. One of them is `Indices` 
that is basically what we want to use.
   
   So, the idea is to make another public API `filter_with_indices` that 
accepts indices to do filtering. The API can build a 
`IterationStrategy::Indices` internally to do filtering.
