feature request: include & exclude function paths

[juanpprieto]

Thanks for the plugin.

Would be great if you could add include and exclude also for function names / paths and not just for env vars.

My problem is that in a nextjs, @netlify/plugin-nextjs generates a huge amount of lambdas and their requires (121 to be precise in my case). Some of these functions, are also pretty massive 500Kb to mbs depending how heavy a given "api" route is.

In my simple use case, I want to pass only one env bar netlify's process.env.BRANCH to just one single function, but the plugin is processing all the hundredths of .js files via babel which takes a huge amount of time killing my build minutes.

Anyway, thought I'd throw in here since nextjs is becoming pretty popular within netlify.

thanks again. JP

Happy to submit a PR.

Just wanted to bump this feature request! We're also looking for a way to workaround the underlying platform limitation that this plugin solves with Next.js and hit a wall with the latest version of the Netlify build plugin: https://github.com/netlify/netlify-plugin-nextjs/issues/751
