Snyk's (try) require

This package tries to load and parse a package.json file. This does not load the package into memory (as per require).

What snyk-try-require does:

- Returns a promise
- Does not throw if the package.json can't be found, but fulfills with null
- Uses debug module under the snyk:resolve:try-require key
- Uses lru-cache for caching for 100 objects for 1 hour
- Adds dependencies and devDependencies if they're missing
- Adds __filename containing the full original path to the package
- If a Snyk policy is present, will add the path of the policy to the snyk property
- If the package uses npm-shrinkwrap.json will include a shrinkwrap boolean property
- Returns the leading and trailing whitespace of the original package.json file as a leading and trailing property respectively
