Add support for big-endian SARCs

[mariomadproductions]

They are used in Wii U games. They are the same, but use big-endian, not little-endian.

Thanks for pointing that out. I will implement that.

@Gericom theres a bunch of file types that have a endianess identifier, might be worth implementing it for all ?

[Gericom]

I implemented BE support for sarc files (using EndianBinaryReaderEx, ReadObject and the BinaryBOM attribute). I did not test it, because I don't have any big endian sarc files, so if one of you could test it...

I can confirm that it does indeed work fine, just tested it on Super Mario 3d World SARC files.

@Sammi-Husky Thanks! Case-Closed

Could you add support for displaying the filename, like in WiiUExplorer?

[Gericom]

I don't have any sarc files with filenames. Could you send me one?
