   I made some change to skip alignment check in `From<Buffer>` and let `Deref` panic when trying to deref a `ScalarBuffer` as `[T]`. However, currently a `ScalarBuffer` is assumed to be access as a slice using slice APIs, e.g., getting offset through `OffsetBuffer`. And we already expose these scalar buffers as slice, e.g.  `GenericByteArray.value_offsets`. To get rid of these slice assumption seems some breaking changes.
