allow []array on bitField #2647
Description
When I use bitfield to operate data , I can only indicate each one. It's very not easy to use. So I quote 'appendArgs' to transform.
before
client.BitField(ctx, "mykey", "INCRBY", "i5", 100, 1, "GET", "u4", 0)
after
client.BitField(ctx, "mykey", []interface{}{"INCRBY", "i5", 100, 1, "GET", "u4", 0})
