v3.2.0

This release has the following major improvements:

• feat: Switch to FreeBSD getopt library
• feat: Automate creating amalgamation distribution
• feat: Add options to use getopt_long_only
• fix: Potential string overflows
• fix: Avoid GCC optimization errors for trex_compile
• chore: Make examples using the static library
• docs: Detect memory issues with ASan and Valgrind

Since we've automated the amalgamation distribution generation, we will start to provide the distribution archives again.
