Decode additional Frameowork16 and AMD related memmap items

TODO:

- [ ] Handle it better than just increasing EC_MEMMAP_SIZE*2
- [ ] Figure out all items and whether they apply to Lotus and also Azalea
- [ ] Figure out Lotus and Azalea fan names

Example:

```
cargo build && sudo ./target/debug/framework_tool --driver portio --expansion-bay
