Dear AppVeyor,

Is it possible to update VCPKG, or at minimum the boost package, because updating to the latest version now causes always to rebuild all boost packages and that takes a very long time:

cd "C:\Tools\vcpkg"
git pull
.\bootstrap-vcpkg.bat
.\vcpkg update

The following packages differ from their port versions:
    boost-iostreams:x86-windows 1.72.0 -> 1.72.0-1
    boost-modular-build-helper:x86-windows 1.72.0 -> 1.72.0-1
    bzip2:x86-windows 1.0.6-4 -> 1.0.6-5
    liblzma:x86-windows 5.2.4-3 -> 5.2.4-4
    zlib:x86-windows 1.2.11-5 -> 1.2.11-6
    zstd:x86-windows 1.4.0-1 -> 1.4.4

.\vcpkg upgrade --no-dry-run

The following packages will be rebuilt:
  * boost-accumulators[core]:x86-windows
  * boost-algorithm[core]:x86-windows
  * boost-asio[core]:x86-windows
  * boost-assign[core]:x86-windows
