Doesn't work with hoisted dependencies in monorepos

[rassie]

In monorepos, especially managed by lerna or pnpm, npm bin doesn't return the correct binary directory, since a binary can be either hoisted to the root directory of the monorepo or be located in the package's node_modules. Solving this would probably require adding both the monorepo's node_modules/.bin as well package's node_modules/.bin to the path.

Hmm. It seems to work somewhat correctly if I set add-node-modules-path-command to pnpm bin, since it's also capable of resolving paths in npm and yarn projects.

This might be easily solved with a recursive function until node_modules does not exists since exec_path admits a list of paths.

Hi! The first implementation actually used to recurse, but we got rid of it due to security concerns: #15

I think if setting add-node-modules-path-command works as @rassie described then this is definitely the way to go.

Ideally I would be able to have a list of commands and this would add all the successful results:
For example

(setq add-node-modules-path-commands '("npm bin" "pnpm bin -w"))

This way I could have both binary in the local package and in the workspace package (if any) - and it would work with both npm and pnpm packages with the same config.

I don't have time for it but it sounds useful. If you send a PR I'll look at it.
