Broken SPIRV-Reflect sub module

[olihey]

The commit you are using for SPIRV-Reflect does not exist anymore https://github.com/KhronosGroup/SPIRV-Reflect/tree/eead52925f913255b3ec64d61eb8836bdf4bebe8
This results in a compile error when checking out gatling fresh :(

Hi, thanks for the notice! Seems like I didn't change the revision when I changed the remote, and for some reason it still works in the CI. I've updated the submodules on the dev branch.
