* Remove a bit of unsafety around
* Regenerate StructArrayHelpers with a max element value of 256
* hle: remove unsafe marker from all struct that had it
* hle: make SoftwareKeyboardRenderer.TryCopyTo safe
* hle: remove unsafety in NpadDevice and remove AllowUnsafeBlocks from csproj
* Revert "Regenerate StructArrayHelpers with a max element value of 256"
This reverts commit f32a6e5be0
.
* Introduce ByteArray of various size and use that instead of ArrayXXX to avoid stackoverflow in .NET runtime type resolution
* Use ByteArray more
* Add some missing spaces on Pack = 1 for various structs
* Fix broken logic for TryCopyTo
* Address gdkchan's comment
* Address gdkchan's comment
