No support for nested arrays

[niekvanderkooy]

Especially within transactions, nested arrays are something which occurs quite frequently
For example,

MULTI
LPUSH foo bar
LPUSH foo bar
LRANGE foo 0 -1
EXEC

returns

1) (integer) 2
2) 1) "bar"
   2) "bar"

However, this is currently not supported by aredis. Although the rrt_array_value exists, the above
EXEC command will return two rrt_integer_value types for the LRANGE commands, and a single rrt_string_value for the second command (which does contain both the bar values, but is not formatted correctly since the string contains `bar\r\n$3\r\nbar\r\n" with a length of 3.

Hmm, I make a big mistake (lol).
To fix it, I need a big change.
Let me try to fix it.

Support nested arrays now.
