Support for 88.0+ Custom Components structure

[drewrox2009]

I can see that you haven't worked on this project in a while, which i understand it works smoothly. I am just getting anxious on the approaching drop in support for the older structure. I am not sure what is required to change in the python file to support the new layout.

If anyone else is reading this, to get HANotify working again,
you need to create a "fcm-android" folder in the custom_components directory.

<config>/custom_components/fcm-android

in it, you need to add:

• the old 'fcm-android.py' file renamed to notify.py
• a blank file named __init__.py
• a file named manifest.json containing

{
    "domain": "https://github.com/Crewski/HANotify",
    "name": "HANotify",
    "documentation": "https://github.com/Crewski/HANotify",
    "dependencies": [],
    "codeowners": ["@Crewski"],
    "requirements": []
  }

Then restart Home Assistant and you should be good.
