Add armhf/arm64 Docker images

[LouisMT]

Seems like a great project which I would like to use on my Raspberry Pi.

However, at the moment there's only a prebuilt amd64 Docker image. Could armhf (current Raspberry Pi OS) and arm64 (ARM servers/64-bit Raspberry Pi OS) be added?

@LouisMT I agree this will be nice. I’ll have to check though, I’m not sure if Tokio actually supports ARM because it uses MIO.

I am also very interested in supporting the ARM64 platform.
I have prepared an image for my own use:

That sounds great @MuratovAS , do you use it? Does it work well on ARM?

I've been using this image for 3 days on my rpi4 and haven't noticed any issues. I don't think there will be any issues, I haven't changed the code of the app.

The images for unFTP it built and deployed via Github actions. See here. You can add the arm image there if you like. Images for CI you can find here.
