Summary:
`jimp` is used by `favicons-webpack-plugin` via two different paths.
Upgrading `favicons-webpack-plugin` upgrades one of the dependent `jimp`s
Force resolve `jimp` to the same version so that the other dep also uses
the same one.
(`jimp` itself seems to have a fairly stable api, except for one somewhat
breaking change in `v0.10.4`)
