LibDMDUtil segfaults if DMD is bigger than 256 * 64

[francisdb]

https://vpuniverse.com/files/file/11755-hellraiser/ has the following code:

Const LCDScreen = True 
Dim UseFlexDMD
If Table1.ShowDT = True then
    UseFlexDMD = False
Else
    UseFlexDMD = True
End If
If LCDScreen = True Then
  FlexDMD.Width = 512
  FlexDMD.Height = 128
End If

However this segfaults in the code below as the buffer is limited to 256 * 64

libdmdutil/include/DMDUtil/DMD.h

Line 112 in f54f084

uint8_t data[256 * 64 * 3];

Since the user an configure any width/height in the script this should support any size?
