Given a name, make a unique name even on case-folding filesystems.
If the name is all lower-case, return it unchanged.
If the name contains upper-case characters, append "_xxxxxxxx" where the x's are the first 8 characters of the SHA-1 hash of the name.
var cu = require('case-uniquify')
console.log(cu('jsonstream'))
// output: jsonstream
console.log(cu('JSONStream'))
// output: JSONStream_50850eed
