WIP: ska3-prime

[javierggt]

These are changes to update core packages. It uses python 3.10. The process to make this is roughly described in the wiki.

To install:

conda create -n ska3-flight-2023.0rc4 --override-channels \
  -c https://icxc.cfa.harvard.edu/aspect/ska3-conda/prime \
  ska3-flight==2023.0rc4

This is work in progress, these are some of the known issues:

• ska3-perl is not updated
• does not include windows updates
• It fixes most issues about updating externals
  • coverage is missing
• does not fix the following issues (it should):
  • missing pyqt in ska3-core-latest? #969
  • Installing the latest ska3-flight, then replacing it by ska3-flight-latest should be a no-op. #967

the process has these issues that I had to solve manually:

• fails to fetch the right quaternion package.
• the process installs pyqt5-sip from the pypi platform.
• the resulting ska3-flight does not include ska3-core as dependency.

I ran tests:

• HEAD: dashboard | log
• Mac OS: dashboard | log

I've been fiddling with this on linux with the starcheck use case. I just ran into jplephem is missing on the Python side.

Oh, that's probably because ska3-core isn't a dependence. I'll try that.

Do we still need this PR @javierggt? or is this superseded by #1008 ?

I used this branch to make the 2023.1 branch. Should not be needed anymore.
