🐛 Describe the bug

When I ran validate (3.3.0-SNAPSHOT) against a pds4 label with special constants for a product with a SignedLSB2 data type, I noticed that validate blew up with a FATAL_ERROR

🕵️ Expected behavior

I expected validate to validate the pds4 product without blowing up with a java error.

📜 To Reproduce

1. Download product and label from https://pds.lroc.asu.edu/data/LRO-L-LROC-3-CDR-V1.0/LROLRC_1055A/DATA/ESM5/2023075/NAC/M1433566422LC.IMG and https://pds.lroc.asu.edu/data/LRO-L-LROC-3-CDR-V1.0/LROLRC_1055A/DATA/ESM5/2023075/NAC/M1433566422LC.xml
2. run validate against the xml file
3. FATAL_ERROR [error.array.bad_file_read] array 1: Error occurred while reading data file: class java.lang.Short cannot be cast to class java.math.BigInteger (java.lang.Short and java.math.BigInteger are in module java.base of loader 'bootstrap')

@kbowley-asu I can replicate the issue. We will add this to the backlog. What is the urgency on this fix?

[kbowley-asu]

Due to the various updates to validating Special_Constants, version 3.1.1 is the last version of validate that we've been able to use. I just noticed this bug when I tried using the latest SNAPSHOT version while working on some tweaks to our tools that generate PDS4 labels for our products.
