Update: Add script for generating Unicode Codepoints from integers.

Update: Add script for generating Unicode Codepoints from integers.

A simple script that I am using for generating a range of Unicode Codepoints in the format needed by the generate_unicode.sh script.
The private use area is represented by multiple sets of all values within some range.
These ranges are a massive list.
This script generates these.
The only thing I need to do is use a calculator program to convert hex to integer.
These integers are then passed to the script as an inclusive range.
