ImGuiKey_ has been renamed to ImGuiKey #220
Description
Whilst helping a user in the SFML Discord server I noticed that a change from a few days ago within imgui now means that it is not possible for a user to grab the master branch and use it with imgui-sfml. It causes build errors associated with the enum ImGuiKey_ no longer being present.
Just thought I would leave an issue up in case someone runs into this. It is possible (and advised imo) to use the most recent stable release of imgui v1.88 instead.
