fix: (Windows) Replace ICO decoder for improved icon extraction

Implemented direct use of `sergeymakinen/go-ico` decoder instead of `mat/besticon/ico`
for icon conversion. The standard `image.Decode()` and  `mat/besticon/ico` approaches
failed with certain ICO files, particularly those containing cursor data
from Windows executable resources. This change ensures more reliable
handling of various ICO format variants.
