Update to Lumina 5 (new Excel parsing)

[WorkingRobot]

New Features:

• Transparent RSV resolution using a hook to LayoutWorld.AddRsvString.
• Removal of ExcelResolver. Lumina.Excel.RowRef works as a better and more featured alternative now that lazy construction is obsolete/useless.
• IDataManager service now accepts a string? name optional parameter for explicit sheet names.
• IDataManager.GetSheet is now split into IDataManager.GetSubrowSheet as well.
• IDataManager.Get(Subrow)Sheet functions now throw. Not sure if this is 100% a good idea, but I don't like quiet failures for stuff that should be constant and never fail (except for updates and sheet changes). If needed, Lumina.GameData.Get(Subrow)Sheet is an alternative to Lumina.Excel.ExcelModule.Get(Subrow)Sheet that throws only when the schema/struct type is invalid.

Until Lumina is updated to v5 and ExdSheets is upstreamed to Lumina.Excel, you'll need to resolve the dll paths by compiling WorkingRobot/ExdGenerator on the new-lumina branch.

Please remove the CS bump. If you need it, let us know so that we can upstream the proper changes. Completed, thank you.

As noted as well, this'll be blocked until Lumina updates itself and/or we decide that we want to maintain our own repo/project separately.

Also, still somewhere on the todo list:

• Write migration guides for changing concepts.
  • Special callout to sheet extensions/additions/calculated methods.
  • Any relevant pitfalls that may occur as part of this new mechanism.
• Figure out how to rapidly update EXDSheets to get changes upstreamed in a timely manner.
• Deal with any other strange dev use-cases that might come up.

Changed this PR to use Lumina.Excel instead. (Use the lumina2 branch)
As long as EXDSchema gets updated, Lumina.Excel can be easily built + tagged + pushed to NuGet.

I'm considering writing some sort of generator to allow users to easily create IExcel(Sub)Row types, which will be made available on NuGet. Some features may include inheritance support and automatic generic RowRef generation (it has an additional hash that should be computed at compile time for a 2x speed increase). If there are any suggestions for this future generator, let me know, and I'll work on including them.
