[Feature] Tasks to add

[StoneT2000]

A list of tasks planned to be added to ManiSkill and eventually come with demos.

• [ ] OpenCabinetDrawer
• [ ] Multiple drawing related tasks
• [ ] Clean table task (2 versions, robot with "sponge" attached" and one without probably)
• [ ] Long horizon pyramid building tasks
• [ ] More "household" type of tasks, which dynamically are not any more difficult than table-top but "look" more realistic and interesting
