Loader sets wrong PPC language by default #22

By default loader select "PowerPC:BE:64:VLE-32addr", "default" https://github.com/zeroKilo/XEXLoaderWV/blob/4ecd656db0a0fa30976abd3693c5e606c5985edd/XEXLoaderWV/src/main/java/xexloaderwv/XEXLoaderWVLoader.java#L42

As far as i know Xenon is not VLE processor and support only fixed length opcodes (4 bytes). Due to wrong processor type, Altivec support is missing. Correct selection should be: "PowerPC:BE:64:A2ALT-32addr", "default" . Otherwise, there is no way to decompile/disassemble code like in screenshot: image

Of course, Ghidra still fail to recognize VMX128 specific instructions, but that require additional work on language files.

Thanks! Everything beside VMX128 works as intended now.
