Reduce size of several PDFium constant tables.

Either by using the smallest possible data type, or
By accurately calcuating the bounds, or
Moving to array of pointers for varying length rows.

Notes:
The 929 is reassuring since PDF417 barcode uses GF(929).
FX_WCHAR is 4 bytes on unix (2 on windows).
Binary looks to be about 240k smaller on linux/64
