Substituted grunt-zip for grunt-contrib-compress

[Beak-man]

Description of the Change

Substituted development dependency grunt-zip for grunt-contrib-compress.

The latter is more actively maintained, has more robust binary data handling and better cross-platform compatibility.

https://github.com/gruntjs/grunt-contrib-compress

Note that grunt-contrib-compress uses a different library for compressing (archiver) compared to grunt-zip, which uses jszip, which in its turn is also used as one of the few external dependencies within the engine itself. A review of jszip's functionality within Web WorldWind is in order to consider its substitution.

Why Should This Be In Core?

At some point, grunt-zip began producing a corrupt bundle release artifact. See #900

Benefits

Artifact .zip bundling now works OK.

Potential Drawbacks

None found.

Applicable Issues

• [nitpick] The indentation for this cwd property is misaligned compared to other entries; aligning it with the surrounding properties will improve readability.

                        cwd: 'build/dist',

[Copilot]

[nitpick] For consistency with the dist task and to ensure a predictable folder structure inside the archive, consider adding cwd: 'images' and changing src to ['**'] under the images files block.

Suggested change

	src: ['images/**']
	cwd: 'images',
	src: ['**']

[Copilot]

[nitpick] Using the maximum compression level (9) can slow down build times; consider using a lower level or the default setting if ultra-high compression isn’t required.

Suggested change

	level: 9
	level: 6
