Out of curiosity, why can't the entire document be merged unconditionally?

Developers working on Vulkan features not yet merged into vk.xml had no way to test against the spec without modifying it directly.
This adds an --extension-file option that accepts a path (or comma-separated list of paths) to additional XML files, which are merged into vk.xml at runtime — allowing users to prototype and test new extensions without touching the upstream spec.
Usage:
glad --extension-file VK_test_extension.xml ...
glad --extension-file VK_ext_a.xml,VK_ext_b.xml ...
