add notify as provider

[K0IN]

PR for: #465

Open demo instance and subscribe, then run the code:

from notifiers import get_notifier
p = get_notifier('notify')
print(p.required)
res = p.notify(title='test', message='test', base_url='https://notify-demo.deno.dev', tags=['test'])
print(res)

a local test instance can be hosted like so (warning, hardcoded key):

docker run -p 8787:8787 -e VAPID_KEY=eyJrdHkiOiJFQyIsImNydiI6IlAtMjU2IiwiYWxnIjoiRVMyNTYiLCJ4IjoiMGh4bURpNmRIWkJFQmx3MmZBOTVka09mNktSSHllc2NRb3JNV2dMNGR6TSIsInkiOiJCZnNYZ2tnMW9iWHMybmpmTWRyMmVDZ1FPZmFoVWE3WWtWczFuVzdfeWxVIiwiZCI6Ind4X3N5TmFkSFZ3OHhHOExVQzJhcWF2OG8zZVlQWEtVRmdEdDFDNm80b1UiLCJrZXlfb3BzIjpbInNpZ24iXSwiZXh0Ijp0cnVlfQ== -e SUB=mailto:admin@admin.com -e SENDKEY=mypassword ghcr.io/k0in/notify:latest

Where token must be set to "mypassword".

from notifiers import get_notifier
p = get_notifier('notify')
print(p.required)
res = p.notify(title='test', message='test', base_url='http://localhost:8787', tags=['test'], token="mypassword")
print(res)
