Allow to remove the warning of lifecycle scripts for npm packages

[oscarotero]

There are some NPM packages that have lifecycle scripts that are not needed in Deno.

For example, Lume uses sharp to transform images, and this package has an install script only to check if everything is okay. I suggested to sharp maintainer to remove the script but it looks like it's useful in some contexts (but not applied to Deno). lovell/sharp#4318

The warning shown by Deno is a bit confusing and some people think it's an error. I'd like to have a way to omit these warnings. Maybe an option in deno.json file, for example:

{
   "ignoredLifecycleScripts": ["sharp"]
}
