Breaking changes

Changes to the Parser type (#272)

The parser type now only persists the buffer and takes the Read instance in parse_value. redis::parse_redis_value is unchanged and continues to work.

Old:

let mut parser = Parser::new(bytes);
let result = parser.parse_value();

New:

let mut parser = Parser::new();
let result = parser.pase_value(bytes);
