• docs: Describe vcpkg support
• fix: Add -Wconversion to fix type conversion issues
• feat: Use BUILD_SHARED_LIBS to control lib type
• fix: Add version.tag to release archives

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.

This release has the following major improvements:

• fix: GCC8 and later gives warnings for strncpy and strncat
