handle peerDependencies

[davideicardi]

If when installing a package we found that there is one or more peerDependencies not available inside staticDependencies throw an error.

From #24 :

Installing peerDependencies automatically would be unexpected for people who are used to NPM/Yarn behavior. From my understanding, it seems like staticDependencies could play well with peerDependencies. For example:

• package A specifies peer dependency X
• my project installs & requires package A using live-plugin-manager
• live-plugin-manager will not install X
• (new behavior) if my project does not pass X via staticDependencies, live-plugin-manager will error or warn (just my 2 cents)

What about add an option to install peerDependencies?

@ylc395 Yes agree, it could be an option.
