* debian/patches:
   - Use the SIMD Everywhere headers from libsimde-dev, instead of upstream's
     code copy
* debian/control
   - Build-dep on libsimde-dev
   - Add "Built-Using: ${simde:Built-Using}" to all the binary packages to
     document the version of libsimde-dev used, as required to keep that
     version in the Debian archive, which is needed to fulfill the GPL
* debian/copyright:
   - exclude libobs/util/simde/* as we will use the files from libsimde-dev
* debian/rules:
   - Include the recommended flags for SIMDe, especially important for
     non-X86 architectures
