Brute Forcing Master Branch Version of Animatediff, into Forge/Master to Enable Freeinit

[leomaxwell973]

Take caution, as this is mostly the "Master" aka vanilla webui version, rather than the forge version, may have compatibility issues as well as performance downgrades/rollbacks. But, it's the Vanilla version of AD, but on forge, with the objective of getting Freeinit available in forge only installs.
Start with the "Master" branch of AD, then, overwrite the following lines of code.
