Feature Request: LitHex, LitBit, LitOct

[bangzek]

I work on low level binary protocol stuff and need to generate file using jen. I wish there's LitHex and LitBit so my generated code could use 0xFF and 0b1111_0000 literal.

Can you give me examples of this syntax used in code?

[bangzek]

Take this code:

	f := NewFile("util")
	f.Func().Id("positive").Params(Id("b").Byte()).Bool().Block(
		Return(Id("b").Op("&").Lit(0x80).Op("==").Lit(0x00)),
	)
	fmt.Printf("%#v", f)

which will generate:

package util

func positive(b byte) bool {
	return b&128 == 0
}

I want to change the output b&128 to b&0x80 so it would be clear to human why it using that magic number.

I hope it clear to you.
