After seeing the performance of this plugin degrading I investigated and found out that dependencies where copied during packaging.

This takes ages to complete. Normal packaging of project takes a bit less than 1 minute. Then with more dependencies added it goes up to 6 minutes.

Went to see how serverless-esbuild was managing it and they just don't copy and add files directly to the zip. Which makes sense. Why copying around node_modules?

See: https://github.com/floydspace/serverless-esbuild/blob/8a1dcc02c49574c0b04df084a3b79049b4e8e25f/src/pack.ts#L197

If I have the green light from authors I can work on this and create PR to address this problem.
