Bug in v0.1.5 visium_hd reader

[t-a-m-i]

Hi, I get an error when trying to read in a Visium HD dataset with the visium_hd reader of v0.1.5. The same code works perfectly fine with v0.1.4.

from spatialdata_io import visium_hd
sdata = visium_hd(
    path_read,
    load_all_images=True,
    fullres_image_file=fullres_image_file,
    dataset_id=dataset_id
)

Throws:

FileNotFoundError: [Errno 2] Unable to synchronously open file (unable to open file: name = '/files/03-SpaceRanger-Results/P31904_402/outs/P31904_402_feature_slice.h5', errno = 2, error message = 'No such file or directory', flags = 0, o_flags = 0)

"P31904_402_feature_slice.h5" indeed does not exist, it should simply be "feature_slice.h5" in "outs" of the "P31904_402" folder.

Here is the full traceback:

Thanks for reporting. Tagging @melonora, the bug seems due to #204 and #206.

[LucaMarconato]

Partly related to #212

[LucaMarconato]

The issue should now be addressed thanks to #264. Please if you test the new fixed code, it would be great to learn your feedback.
