ByteSize symbols should be translated

[jeremyVignelles]

Hi,
I'm French, and I'm using Humanizer to display TimeSpans and Byte size in a human readable-format.

However, in France, the term "byte" doesn't exist, except for programmers, and the word "octet" is used instead.

A few examples of english units VS french ones :

• MB => Mo
• kB => ko
• kb => kb

When non-technical folks read "MB", they will read it as "Méga Bits", which is a bit different.

For reference, here is how Windows shows the file sizes:

I've begun implementing this... I too feel that data unit symbols should be displayed according to culture.

Just submitted an initial version. It could be simplified a bit, but I strove to limit breaking API changes... If that's not a concern, I could give it another shot.
