Require await in async

[kvc0]

disallows using await outside of an async def scope

await ''  # syntax error, not async def (also '' is not awaitable but this does change not fix that)

def f():
  await ''  # syntax error, not async def

def f():
  async with real_async_function() as a:  # syntax error, not async def

def f():
  async for i in arange():  # syntax error, not async def

Yep, should be.

Why is this being deleted? Maybe you need to merge adafruit/main into your branch?

[tannewt]

Nevermind. This was my mistake in my PR. This was an error I added but deleted before merging. 🙄

Looks good! Thank you!
