wv-2442 Vector Flow Prototype

[Tomcariello]

Description

Vector Flow Prototyping. Add ASCAT & OSCAR layers with animated visualizations. Include MISR Cloud Motion Vector layer (just for comparison). Implement UI for user input for visualization (static or animated, color palette, etc.)

How To Test

• Load at least 1 base layer (I like Blue Marble, August 2004 shaded relief). The animation will work with any base layer but it doesn't stand out well if there is cloud cover.
• Set the date to January 01, 2020 for OSCAR or ASCAT. Use March 21, 2020 for MISR.
• Add layer ASCAT/OSCAR/MISR from the layer picker.

Notes

To test static/animated representation, set renderAscatAnimated to false (line 55 in layerbuilder.js). This will be moved to the UI as progress allows.

Caveats

When loading the animation, overlay layers can be added/removed but adding/re-ordering base layers is not yet working. Not supported on mobile.
