Axes swapped when using Image backend TIFFfile

[sinberlin2]

Describe the bug
Tiles are sampled outside WSI bounds, causing an error. 'Requested region outside level boundaries'. This is due to axes being in the opposite order when reading in the mask using the Imagebackend TIFFfile as opposed to using ImageBackend PYVIPS.
So as an example:
self._wsi.slide_bounds (in _image.py)
Pyvips backend:
((0, 0), (3758, 2402))
Tifffile backend:
((0, 0), (2402, 3758))

To Reproduce
The issue occurs when creating a tiledroidataset from a wsi and a corresponding mask, where the mask is read in with the ImageBackened TIFFfile.

Expected behavior
The mask boundaries should be the same no matter whether it is read using ImageBackend TIFFfile or PYVIPS.

Environment
dlup version:

Hi! Can you check the behavior as well using openslide as backend?

I looked at it in a bit more detail, and it's called here:

dlup/dlup/backends/common.py

Line 171 in 3271be1

def slide_bounds(self) -> tuple[tuple[int, int], tuple[int, int]]:

So I would assume that more axis are swapped in the tiffbackend. Before we fix this, we should merge #185
