Fix: Added fix for rate_limit_delay attribute error, resolved async wait

[paimonsoror]

This should resolve the errors with the rate_limit_delay function, as well as subsequent async related errors that happen afterwards.

Resolves: #216

[gabosom]

good catch!

[Mr-HaleYa]

#235 is more thorough with the addition of error logging on fail

[gabosom]

this will fail, the function needs to be defined as async

[gabosom]

I tried the changes manually and they seem to work but this PR making the line 96 function definition async.

[paimonsoror]

@gabosom odd, I could have sworn I tried that and still got errors. So did you set the def as a sync and keep the await?

I can give that another test and update the PR

[Mr-HaleYa]

When the await is added

success = await hass.config_entries.async_forward_entry_unload(entry, component)
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: 'await' outside async function

After changing to async def _unload_component_entry the error goes away but 2 new errors appear

But I think they are caused by me currently being rate-limited.
