OPTIC not available for arm64

[victorpaleologue]

Using Docker on a Mac M1 (arm64), I try to run OPTIC:

(planutils) root@8f6fe7a98cf4:~$ optic

Package not installed!
  Download & install? [Y/n] y
optic will be installed.

About to install the following packages: optic (297MB)
  Proceed? [Y/n]

Successfully installed optic!

Original command: optic 
  Re-run command? [Y/n] 
FATAL:   could not open image /root/.planutils/packages/optic/optic.sif: the image's architecture (amd64) could not run on the host's (arm64)

It fails because the binary package downloaded by planutils is for amd64.

Isn't this a copy of #93 ?

Not to me...
This issue is about one specific package is for amd64, not arm64.
#93 is about the docker image to be buildable on arm64.
I have a PR #94 that can fix #93 and allows me to use some planners, but OPTIC.
The fix for getting OPTIC to work there will definitely be a different one.
