feature: use custom avatar from wechat per msg

[wey-gu]

A avatar cache should be built to custom msg sender's profile image.

• [x] support generating random emoji as an avatar, via #6
• [x] support upload avatar to object storage with URL and pass to slack(seems to be the only way to specify avatar)
• [ ] A way better/cooler proposal is WIP by @frostming to create a service to generate URL of avatar w/o needing to actually put files there.

Now it's something like this:

TBD:

• [x] We could hash username and mod it to emoji avatar index to "fix" generated emoji, then no cache is needed, too. by @frostming via https://github.com/wey-gu/chatroom-syncer/pull/12
• [ ] Need to revisit the current emoji list, to remove the embarrassing ones

Disagree with introducing extra dependencies. I will try a serverless solution that generates the image URLs from the base64 data. Something like:

https://make-image.serverless.app/${base64}

Indeed it has been worked out with CF worker(yeah, THANKS TO ChatGPT), try visiting this URL. I am currently stuck by not able to get the contact avatar..

P.S. the API spec is:

https://mkimg.frostming.workers.dev/${base64_url_encoded}.${ext}

[wey-gu]

Aha, my regular expression was written by ChatGPT, too :P

It worked like a charm! I am not familiar with the price model of CF worker, as it will require CF's edge computing resource to decode and respond with those small images, will this be scaling to anyone? (that is, we can place your single CF-worker-based endpoint by default to expect it will work for long? or do we need users to setup their own avatar base64 ping-pong service same as yours?

Oh, I encountered this, too, this is hard as python lib is just a wrapper and the gateway is the major part(hard for me to debug) :(

anyway, I will look into it later, too, I have to prepare for the slides of tomorrow now 🤦🏻‍♀️.

[frostming]

Indeed, but the error message argument of type 'NoneType' is not iterable indicates that it may come from Python code. Let's see.

@frostming If the ContactAvatarResponse, and ContactAvatarRequest gRPC interface issue cannot be mitigated anyway, we could still leverage your CF worker URL encoded magic to add our customized avatars :)

I came up with an EVIL approach to fix the issue in a DIRTY way, let me check.

Wow, this sounds neat...😏
