does't work on IIS

[maxiaojunwolf]

it works when i use uvicorn to start ther server,but HTTP 500 when i start it by IIS

[maxiaojunwolf]

the reason is:
the 'on_startup' function does't be called on IIS,so the "await FastAPILimiter.init(cache)"also does't be called

my solution:
try to call FastAPILimiter.init on server starting,
FastAPILimiter.redis = cache
FastAPILimiter.prefix = "fastapi-limiter"
FastAPILimiter.identifier = default_identifier
FastAPILimiter.callback = default_callback
FastAPILimiter.lua_sha = 'a3f9e982197e9e887f6b5dcb7ec273863bb83aad' (use uvicorn start first get the SHA value,otherwise you need an async function,actual you can use this value direct)
