CLI compile-folder exception when data is invalid

[lucasff]

In @formatjs/cli if any of the source JSON used to be processed by the compile-folder command, this exception is thrown:

TypeError: Cannot read property 'charCodeAt' of undefined

Expected behavior
I'd expect the error to be nicer, maybe informing the file and/or key that fails?

Yup thanks a lot for reporting we'll take a look
