Upgrade gif playback library / first time run memory usage improvement

Description

When starting for the first time EarTrumpet consumes large amount of memory, this is likely because: Currently for the initial intro screen WpfAnimatedGif library is used for Welcome.gif playback but the same author has an improved library XamlAnimatedGif - one of the key improvement being:

Resource efficiency The old library used an awful lot of memory, because of the way it worked internally (prepare all frames beforehand, keep them in memory and assign them in turn to the Image control). XamlAnimatedGif renders the frames just-in-time using a WriteableBitmap, so only one frame at a time is loaded in memory. The CPU usage is still small, unless the image is very large. Also, since the Image.Source property doesn't change during animation, it avoids triggering a layout pass every time.

Steps to reproduce

1. Install program.
2. Open for first time, see intro screen.
3. High memory usage.
4. Closes window, memory usage does not drop immediately.

Meta

• EarTrumpet version: 2.1.8.0
• Windows 10 version: 19042.985

Additional context

Not a priority, once GC does its thing the memory should drop eventually.
