Segfault when reading invalid TGA data

[mwestphal]

Describe the bug
F3D added support for displaying images as texture recently, however when providing an invalid image, it can segfault

To Reproduce
Steps to reproduce the behavior:

1. Download this file autzen.zip
2. Open the file using f3d --no-config --force-reader=TGA autzen.pts
3. segfault/assert
