Review comment:
@velvia In the current version you could use the
`bitwise_bin_op_helper`from `buffer.rs` if you make that public. That calls
your bitwise operation with two `u64` as an input and takes care of the offset
alignment.
In our internal codebase we have similar functions also for 3 or 4 inputs,
which would come in handy for you usecase, since you could calculate the result
without the temporary `right_combo_buffer`. So you could also think about
copying that function and modifying to take a function of 3 parameters instead.
