[issue41226] Supporting `strides` in `memoryview.cast`

[issue41226] Supporting `strides` in `memoryview.cast`

New submission from jakirkham : Currently one can reshape a `memoryview` using `.cast(...)` like so... ``` In [1]: m = memoryview(b"abcdef") In [2]: m2 = m.cast("B", (2, 3)) ``` However it is not currently possible to specify the `strides` when reshaping the `memoryview`. This would be
