Instead of retrieving the entire list of items/characters/scores/etc. at once (and even store them in memory), use SQL's `LIMIT ... OFFSET ...` pagination so we only take what we need.
Currently only CHUNITHM uses this, but this will also affect maimai DX and O.N.G.E.K.I. once the PR is ready.
Also snuck in a fix for CHUNITHM/maimai DX's `GetUserRivalMusicApi` to respect the `userRivalMusicLevelList` sent by the client.
### How this works
Say we have a `GetUserCharacterApi` request:
```json
{
"userId": 10000,
"maxCount": 700,
"nextIndex": 0
}
```
Instead of getting the entire character list from the database (which can be very large if the user force unlocked everything), add limit/offset to the query:
```python
select(character)
.where(character.c.user == user_id)
.order_by(character.c.id.asc())
.limit(max_count + 1)
.offset(next_index)
```
The query takes `maxCount + 1` items from the database to determine if there is more items than can be returned:
```python
rows = ...
if len(rows) > max_count:
# return only max_count rows
next_index += max_count
else:
# return everything left
next_index = -1
```
This has the benefit of not needing to load everything into memory (and also having to store server state, as seen in the [`SCORE_BUFFER` list](2274b42358/titles/chuni/base.py (L13)).)

I had been itching for the favorites feature since I'm bad with japanese so figured I'd go ahead and add it. I've included a few pics to help visualize the changes.
### Summary of user-facing changes:
- New Favorites frontend page that itemizes favorites by genre for the current version (as selected on the Profile page). Favorites can be removed from this page via the Remove button
- Updated the Records page so that it only shows the playlog for the currently selected version and includes a "star" to the left of each title that can be clicked to add/remove favorites. When the star is yellow, its a favorite; when its a grey outline, its not. I figure its pretty straight forward
- The Records and new Favorites pages show the jacket image of each song now (The Importer was updated to convert the DDS files to PNGs on import)
### Behind-the-scenes changes:
- Fixed a bug in the chuni get_song method - it was inappropriately comparing the row id instead of the musicid (note this method was not used prior to adding favorites support)
- Overhauled the score scheme file to stop with all the hacky romVersion determination that was going on in various methods. To do this, I created a new ChuniRomVersion class that is populated with all base rom versions, then used to derive the internal integer version number from the string stored in the DB. As written, this functionality can infer recorded rom versions when the playlog was entered using an update to the base version (e.g. 2.16 vs 2.15 for sunplus or 2.22 vs 2.20 for luminous).
- Made the chuni config version class safer as it would previously throw an exception if you gave it a version not present in the config file. This was done in support of the score overhaul to build up the initial ChuniRomVersion dict
- Added necessary methods to query/update the favorites table.
### Testing
- Frontend testing was performed with playlog data for both sunplus (2.16) and luminous (2.22) present. All add/remove permutations and images behavior was as expected
- Game testing was performed only with Luminous (2.22) and worked fine
