More sitting pose options.

There is only one sitting pose right now basically just cross legged and it looks the same for everyone with no difference between male and female and it is way too limited. Characters should naturally be able to sit on the various chairs and objects in the world but judging by how things still are even by Season 03 it does not look like that is ever happening. Add more poses like seiza W sit knees up sitting with legs stretched out on the ground leaning back on the hands and more.
