PEL: Add function to generate unique PEL IDs
Create generatePELID() to return a unique 4B PEL ID every time it is
called. It will start at a base value, and then increment by 1 each
time. It uses a file to save the next value to use.
This will be used by the PEL handling code to create unique values
for the error log ID field in the Private Header section.
