Add support for custom lora urls in LoRA Stacker

[guivr]

Fixes #244

[guivr]

Update: now it hashes filenames and only download .safetensors files

[guivr]

Is there anything I need to work on to get this approved? @fofr

I need this to use it in my business (currently using a custom cog)

Thanks

[guivr]

I tried to improve the code + keep the original filename in the beginning of the final filename so that the logs from WeightsDownloader are easier to read and identify which lora it is downloading.

@fofr what do I need to do?

[guivr]

@fofr Hi fofr, you said you’d fix this (#237)

how do you suggest fixing it if not this way?

[guivr]

any feedback?

[guivr]

@fofr what's missing for this to get approved? Why are there no responses? What's wrong with it?

@guivr Can you push to your own fork if you need this urgently?

Yes it's possible but then I have to use my own cog, and it always gets cold/sleeps. any-comfyui is usually warm and starts up faster (less costs)

I think this update is beneficial to everyone because the LoRA Stacker is a node listed as supported by this cog, but it's not fully supported - because it can't load custom LoRA URLs - but this pull request fixes it.
