Add Support for SimpleX Chat - Open source privacy focused messenger

[katoog]

Telegram works great, but there are some privacy sacrifices:

1. Accounts are tied to phone numbers
2. Images posted in groups are not end to end encrypted
3. There have been some questionable encryption design decisions in Telegram's history, making people wonder whether a backdoor exists.

When using Telegram, we're uploading images of our vehicles, number plates, faces of friends, family and our children. Cameras set to monitor backyards will upload a variety of private images to Telegram, cloud encrypted but not end to end.

SimpleX Chat:

• No phone numbers, uses unique ID/invites.
• Security assessment by Trail of Bits
• Option to host your own SMP and XFTP servers
• Desktop, mobile and terminal apps available.

How I picture this might work (user experience):

• User installs App on Mobile or Desktop, creates a group and configure settings (message expiry, group profile image etc).
• Enable option in AI Tool. This creates a SimpleX address (with auto accept enabled) which is needed by the user to add AI Tool as a contact.
• User then invites AI Tool contact to group (with "member" role). User invites other contacts (family) into group to also get notifications.
• AI Tool posts images and descriptions to group.

Lots of stuff available on Github. Here is a chatbot example: https://github.com/simplex-chat/simplex-chat/blob/stable/apps/simplex-bot-advanced/Main.hs
