Typo?

https://github.com/indutny/macho/blob/master/lib/macho/parser.js#L75

```
// Get subtype
var subtype;
if (endian === 'mutliple') // <--- should probably be 'multiple' ?
subtype = 'all';
else if (cpusubtype === 0)
subtype = 'none';
```

Open lib/macho/parser.js at line 75 and inspect the subtype condition around the reported typo. Correct the misspelled value if the surrounding parser logic confirms it, then verify that the subtype branch uses the intended spelling; no test file is mentioned in the issue.
