Parslet::Atoms::Context#try_with_cache

Caches a parse answer for obj at source.pos. Applying the same parslet
at one position of input always yields the same result, unless the input
has changed. 

We need the entire source here so we can ask for how many characters 
were consumed by a successful parse. Imitation of such a parse must 
advance the input pos by the same amount of bytes.
