> implement maps/lists/sets by doing the split for their values in read/write Map/set/list
begin,  For maps, the added problem of a different key/value separator means we have to know
when we're on a key or a value when doing a readString by having some sort of elementIndex.
Hacky, but effective and somewhat like TDenseProtocol - there's nothing to do but to have
state in the protocol and this is preferable to having state in DynamicSerDe since there may
be all sorts of protocols.
