ASCIIi is not supported

[shwao]

You defined ASCIIi as a possible type here:

node-qr/lib/encoder.js

Lines 23 to 24 in fd7f466

	Encoder.prototype.types = ['PNG', 'EPS', 'SVG', 'ANSI', 'ANSI256', 'ASCII',
	'ASCIIi', 'UTF8', 'ANSIUTF8', null];

But you are checking the types with toUpperCase() here:

node-qr/lib/encoder.js

Line 84 in fd7f466

if(self.types.indexOf(cmd_options.type.toUpperCase()) === -1){

Also this line:

node-qr/lib/encoder.js

Line 85 in fd7f466

throw new Error('type must be one of ', self.types.toString());

Should be

throw new Error('type must be one of ' + self.types.join());
