Fix 100035: Make UDIM detection less aggressive
There's been a handful of reports where "obviously" not a UDIM filenames
were detected as such during image open.[1]
This change makes the detection less aggressive by enforcing that the
4-digit sequence be delineated on both sides by one of the following 3
characters ., -, _
This fixes the problem for such filenames as:
"screenshot-1080p.png", "Image-1920x1080.png", "(1999) Photo.png", and
"antiguaChestnut_X_1240Wx814H.png"
