Keep copy of package.json in state storage.

[martinheidegger]

Currently the package.json of each package is loaded before the package data can be loaded.

lambda-plugins/index.ts

Line 262 in 8a03c5e

data = this.package(opts).then(pkg => loadData(this.name, this.path, pkg))

This can be optimized by adding all data of package.json to the state

lambda-plugins/index.ts

Lines 113 to 117 in 8a03c5e

	interface StateFs {
	hash: string
	installed: string[]
	names: string[]
	}

to look something like:

interface StateFs { 
   hash: string 
   installed: {
     [key: string]: Package
   },
   names: string[] 
 }
