Would like an option to override the default JS outputFile (currently, 'svgs.js') #61
Description
The output file is hard-coded to svgs.js, in the app tree.
For projects with lots of SVG files, the size of svgs.js can be very large. Some projects don't have any SVGs on their initial page, so they could lazy load svgs.js separately from the project's main .js file and significantly decrease the time that their apps take to load, especially on a mobile device with a slower network.
broccoli-funnel doesn't seem to be able to exclude the svgs.js file, which would have been a possible solution.
