Fix for loading fields model with file name after "az"

[satsukiyatoshi]

For fields models Kimera only read files until az. Everything after ba, bb and so on will be ignored.

Here's the fix:

in FF7AASkeleton.bas
in Sub ReadAASkeleton

Add (declaration):
Dim fixfield As Integer

Replace:

        If .NumBones = 0 Then   'It's a battle location model
            .IsBattleLocation = True
            For pSufix2 = 109 To 122
                If FileExist(baseName + Chr$(pSufix1) + Chr$(pSufix2)) Then
                    ReDim Preserve .Bones(.NumBones)
                    If load_geometryQ Then
                        ReadAABattleLocationPiece .Bones(.NumBones), .NumBones, baseName + Chr$(pSufix1) + Chr$(pSufix2)
                    End If
                    .NumBones = .NumBones + 1
                End If
            Next pSufix2

by:

        If .NumBones = 0 Then   'It's a battle location model
            .IsBattleLocation = True

            For pSufix1 = 97 To 123
            
                If pSufix1 = 97 Then fixfield = 109 Else fixfield = 97
            
                For pSufix2 = fixfield To 123
                    If FileExist(baseName + Chr$(pSufix1) + Chr$(pSufix2)) Then
                        ReDim Preserve .Bones(.NumBones)
                        If load_geometryQ Then
                            ReadAABattleLocationPiece .Bones(.NumBones), .NumBones, baseName + Chr$(pSufix1) + Chr$(pSufix2)
                        End If
                        .NumBones = .NumBones + 1
                    End If
                Next pSufix2
            
            Next pSufix1
            
            pSufix1 = 97
