Update the LibHac dependency to version 0.13.1. This brings a ton of improvements and changes such as:
- Refactor `FsSrv` to match the official refactoring done in FS.
- Change how the `Horizon` and `HorizonClient` classes are handled. Each client created represents a different process with its own process ID and client state.
- Add FS access control to handle permissions for FS service method calls.
- Add FS program registry to keep track of the program ID, location and permissions of each process.
- Add FS program index map info manager to track the program IDs and indexes of multi-application programs.
- Add all FS IPC interfaces.
- Rewrite `Fs.Fsa` code to be more accurate.
- Rewrite a lot of `FsSrv` code to be more accurate.
- Extend directory save data to store `SaveDataExtraData`
- Extend directory save data to lock the save directory to allow only one accessor at a time.
- Improve waiting and retrying when encountering access issues in `LocalFileSystem` and `DirectorySaveDataFileSystem`.
- More `IFileSystemProxy` methods should work now.
- Probably a bunch more stuff.
On the Ryujinx side:
- Forward most `IFileSystemProxy` methods to LibHac.
- Register programs and program index map info when launching an application.
- Remove hacks and workarounds for missing LibHac functionality.
- Recreate missing save data extra data found on emulator startup.
- Create system save data that wasn't indexed correctly on an older LibHac version.
`FsSrv` now enforces access control for each process. When a process tries to open a save data file system, FS reads the save's extra data to determine who the save owner is and if the caller has permission to open the save data. Previously-created save data did not have extra data created when the save was created.
With access control checks in place, this means that processes with no permissions (most games) wouldn't be able to access their own save data. The extra data can be partially created from data in the save data indexer, which should be enough for access control purposes.

* Haydn: Part 1
Based on my reverse of audio 11.0.0.
As always, core implementation under LGPLv3 for the same reasons as for Amadeus.
This place the bases of a more flexible audio system while making audout & audin accurate.
This have the following improvements:
- Complete reimplementation of audout and audin.
- Audin currently only have a dummy backend.
- Dramatically reduce CPU usage by up to 50% in common cases (SoundIO and OpenAL).
- Audio Renderer now can output to 5.1 devices when supported.
- Audio Renderer init its backend on demand instead of keeping two up all the time.
- All backends implementation are now in their own project.
- Ryujinx.Audio.Renderer was renamed Ryujinx.Audio and was refactored because of this.
As a note, games having issues with OpenAL haven't improved and will not
because of OpenAL design (stopping when buffers finish playing causing
possible audio "pops" when buffers are very small).

* Amadeus: Final Act
This is my requiem, I present to you Amadeus, a complete reimplementation of the Audio Renderer!
This reimplementation is based on my reversing of every version of the audio system module that I carried for the past 10 months.
This supports every revision (at the time of writing REV1 to REV8 included) and all features proposed by the Audio Renderer on real hardware.
Because this component could be used outside an emulation context, and to avoid possible "inspirations" not crediting the project, I decided to license the Ryujinx.Audio.Renderer project under LGPLv3.
- FE3H voices in videos and chapter intro are not present.
- Games that use two audio renderer **at the same time** are probably going to have issues right now **until we rewrite the audio output interface** (Crash Team Racing is the only known game to use two renderer at the same time).
- Persona 5 Scrambler now goes ingame but audio is garbage. This is caused by the fact that the game engine is syncing audio and video in a really aggressive way. This will disappears the day this game run at full speed.
