Treat frame durations <= 10 ms as if they were 100 ms

[qbnu]

The behavior of JPEGView differs from the major web browsers when displaying animated images with frame durations <= 10.
Currently, JPEGView displays all 0ms GIF frames as 100ms, and all <10ms frames (for other formats) as 10ms.
Most web browsers display all <=10ms frames as 100ms:

• Mozilla
• Blink
• WebKit

Some examples that display differently in JPEGView:
0-delay APNG

1-delay GIF (centiseconds)

Thanks for including links and info. I'm learning something new about these animated formats that I haven't ever even thought about, even though things like GIFs are so ubiquitous. It's funny to watch the dog go wild in the current builds 👀
