Joshua Goins 4801c2678a Add new PropertyBase trait, implement more things needed for writing 
The biggest change is that structs and properties now provide their own name,
which is needed when we want to write everything back to a file. Also a bunch of
reorganization of stuff I didn't understand before.

Ireko

Library for reading save files from Dolls Nest. Only the demo is supported because that's what is available at the time of writing.

The parser is almost now complete (save for a few structs like DateTime), and write support is in progress.

Usage

Pass the .sav file you want to read as an argument. Not all .sav files are known to work, such as Level.sav and Player.sav.

        size_in_bytes: 135908,

                size_in_bytes: 135904,
                entries: [
                    Entry {
                        name: "SavedDataVersion",
                        type: Some(
                            Int(
                                IntProperty {
                                    integer_size: 4,
                                    value: 0,
                                },
                            ),
                        ),
                    },

Technical Details

Dolls Nest uses the EasyMultiSave plugin, which saves using the .sav file extension. The save data is zlib-compressed, and decompressing them reveals a very similar tagged structure to GVAS. See more information in this blog post.
