Update module props without needing a texture reload

[kylebarron]

Currently in landsat8.earth, I require a texture reload on every prop change:

    updateTriggers: {
      // Need to expand landsatBands array since comparison is shallow
      getTileData: [
        landsatMosaicId,
        naipMosaicId,
        landsatColormapName,
        landsatBandCombination,
        ...landsatBands,
      ],
    },

For these props (except for BandCombination), it's ok because the actual image texture inputs are changing. But now that I'm supporting more algorithms, things like a filter or sigmoidal contrast parameter changing should not need a texture reload.

I think this is fixed now since I do comparison of whether the images object has changed
