This PR fixes the WebGL texture bug that appears when one frequently changed the point encoding (point color, size, and opacity)

Description

What was changed in this pull request?

  • Fix: destroy the encoding texture before recreating it
  • Fix: reject set() calls if the instance was destroyed
  • Fix: ensures unnecessary color and encoding texture updates are avoided
  • Fix: color and encoding textures are destroyed upon calling scatterplot.destroy()
  • Fix: prevent a minor memory leak in the newly added advanced exporter

Why is it necessary?

Fixes #165

Example

Before

After ~30 draw calls the WebGL described in #165 appears:

before.mp4

After

With this fix, the error does not appear:

after.mp4

I let it run until 1000 draw calls and everything worked just fine.

In addition, this commit:
- rejects `set()` if the instance was destroyed
- ensures unnecessary texture updates are avoided
- color and encoding textures are destroyed upon calling `scatterplot.destroy()`
- fixes a small memory leak in the newly added advanced exporter where I forgot to unsubscribe a draw listener.
