Deprecated Buffer usage in dependency #136

• Version: 5.0.2
• Platform: Windows

Every time I start c8, I get the following warning:
(node:12776) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

This is because foreground-child uses cross-spawn, which uses new Buffer().

cross-spawn has recently finally resolved this issue, but it'll probably take quite some time until the change trickles downstream.

Maybe an alternative module without deprecate feature usage can be used instead?
