Proposal: simplify encoding of numbers in bytestring

The bytestring builder API has a large number of entry points for encoding numbers: int8Dec , int16Dec , int32Dec , int64Dec , intDec , integerDec , word8Dec , word16Dec , word32Dec , word64Dec , wordDec Contrast this with the text library: decimal :: Integral a => a -> Builder I want to deprecate the 11 *Dec functions in favour of the same single-entry-point API used by text: it's way simpler, and no less efficient. (Really, the *Hex functions need the same treatment, but they're less of a priority to me.)
