Allow lit attributes

[wcampbell0x2a]

Working on deku, and I was thinking "the usage " around id is kinda weird? surely we can support not doing this". And this patch does that. I don't know if there is a philosophical reason for all the "? I prefer it not existing, and this patch just allows it to not and exist at the same time.

• Allow Lit::Int for enum id

I went to make the same changes to bytes and bits and low and behold this was already allowed! I changed all references and removed the " from them.

• Remove quotation marks from attribute bytes and bits
