The KiloByteSymbol in DecimalByteSize.cs ([line 14](https://github.com/omar/ByteSize/blob/30bf7f1dba81e57326433647eaf27e2ba4a1a215/src/ByteSizeLib/DecimalByteSize.cs#L14)) is incorrectly declared as "KB". The uppercase "K", is considered an informal (non-standard) notation for 1024 bytes (=KiB). The correct unit prefix for 1000 is lowercase "k". (By the way, one of the Wikipedia articles linked in the readme.md also points this out: https://en.wikipedia.org/wiki/Kilobyte#Definitions_and_usage ;-) )
