[istanbul] Some internal modules are deprecated.

[stein2nd]

npm warn deprecated istanbul@0.4.5:
This module is no longer maintained, try this instead: npm i nyc Visit https://istanbul.js.org/integrations for other alternatives.

npm warn deprecated glob@5.0.15:
Glob versions prior to v9 are no longer supported

npm warn deprecated inflight@1.0.6:
This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
