feat (webpack-image-sizes-plugin): adds option to silence console output

Allows users to suppress console output from the plugin.

This adds a `silence` option to the plugin configuration, which, when set to `true`, will prevent most console logs from being printed. This can be useful in environments where excessive logging is undesirable.
