Support for arm64

[samchouse]

I've tried running theia-full on arm64 Ubuntu (raspi4) and I get a build fail error because I'm on arm64 and not amd64. Could you guys add arm64 support so that I can host on my raspi?

@XenfoMC thank you for the proposal, if you are interested in providing a multi-architecture example (for arm64) of theia-full for example, please don't hesitate to provide a pull-request: https://www.docker.com/blog/getting-started-with-docker-for-arm-on-linux/.

@vince-fugnitto So by that do you mean amd64 and arm64 in the same one or a separate file?

I read quickly the linked article (thanks @vince-fugnitto ), and I may be wrong, but I do not expect that we can achieve running an image like theia-full on a different arch so easily.

I have built and run the Theia example application (Electron) on my own raspi4 and the performance is not great, specially the startup. So I do not think a solution that uses emulation (QEMU) to run x86-64 software on this little arm CPU would work too well, practically (I expect ~5-10x slower than native binaries because emulation).

This leaves the possibility to have an image that's meant specifically for this architecture, on which we install only software meant for it. Maybe starting with a smaller image than theia-full would make it easier?

Maybe, all I know is that my actual computers are so old that if I host Theia it'll "blow up" my computer. I'm not really familiar with the different architectures.
