Useless hash calculation?

[Lukino2000]

Hi,

probably in https://github.com/ligershark/WebOptimizer/blob/d94face378cc9994bb98183ecef1f040b985bac8/src/WebOptimizer.Core/Processors/CssFingerprinter.cs#L73

you can just use info.LastWriteTime.Ticks.ToString()

generate hash is useless unless you do hash calculation on file content...
