[sc-dev] [commit] Return incoming OSC 'b' type arguments in an Int8Array

[Rohan Drape <rd@xxxxxxxxxxxxxxxx>]

The interpreter was returning nil.  Int8Array seems to be the
appropriate type for representing byte vectors in SC.  Since the 'at'
method returns a signed integer value, as expected, the method:

+ Int8Array {
	byteAt {
		arg index;
		var n;
		n = this.at(index);
		if(n.isNegative,{^n+256},{^n});
	}
}

is a useful variant.
