Format file size of p-fileupload

[pmeems]

As I mention here: http://stackoverflow.com/questions/40514986/how-tp-customize-primeng-p-fileupload it is very hard to customize the formatting of the file size in p-fileupload.
It now shows 3 digits which is very confusing.

Perhaps implementing this one is enough: https://github.com/RenovoSolutions/TypeScript-Angular-Utilities/blob/master/source/services/fileSize/fileSize.md

Also adding some option for the developer to easily override the used formatting is very welcome.
