feat: lockfile v3

[dsherret]

This is a proposal that has not yet been agreed upon.

1. Moves npm -> specifiers to packages -> specifiers. Each specifier and destination is now prefixed with npm:.
   • This generalizes with deno: specifiers and allows mapping deno: specifiers to npm:.
2. Moves npm -> packages to packages -> npm.

deno: specifiers will then be stored under packages -> specifiers.

Example output:

{
  "version": "3",
  "packages": {
    "specifiers": {
      "npm:nanoid": "npm:nanoid@3.3.4",
      "deno:path": "deno:@std/path@1.0.0",
      "deno:ts-morph@^11": "npm:ts-morph@11.0.0",
      "deno:@scope/pkg@~1.0": "deno:@scope/pkg@1.0.5"
    },
    "npm": {
      "nanoid@3.3.4": {
        "integrity": "sha512-MqBkQh/OHTS2egovRtLk45wEyNXwF+cokD+1YPf9u5VfJiRdAiRwB2froX5Co9Rh20xs4siNPm8naNotSD6RBw==",
        "dependencies": {}
      },
      "picocolors@1.0.0": {
        "integrity": "sha512-foobar",
        "dependencies": {}
      }
    }
  },
  "remote": {
    "https://github.com/": "MqBkQh/OHTS2egovRtLk45wEyNXwF+cokD+1YPf9u5VfJiRdAiRwB2froX5Co9Rh20xs4siNPm8naNotSD6RBw==",
    "https://github.com/mod.ts": "MqBkQh/OHTS2egovRtLk45wEyNXwF+cokD+1YPf9u5VfJiRdAiRwB2froX5Co9Rh20xs4siNPm8naNotSD6RBw=="
  }
}
