No method to get xoffset/yoffset from SubImage after deprecating bounds() in #2036

[brykgroup-andrews]

As of 0.25.0, specifically in MR #2036, the ::bounds(&self) method has been deprecated. But there has been no way to get the x and y offsets out of that view since that deprecation - is there any way that something can be reintroduced alongside the newly minted ::dimentions(&self) call?

In my case, I use it in a ::change_bounds() call in order to shift the bounds around by a relative margin.

Yeah, removing access to the offsets wasn't intentional. Please feel free to make a PR adding a method on SubImage to access them
