Use arc5gl in ska3

[jeanconn]

Description

Update to use arc5gl from SKA/bin instead of hardwired to /proj/sot/ska/bin/arc5gl (older ska env).

Fixes #3

Interface impacts

The module will now call the arc5gl in the path. It will fail if there is no arc5gl in the path.

Testing

Should be tested with skare3 with sot/skare3#855 .

Unit tests

• No unit tests

Functional tests

I installed this in /proj/sot/ska3/test-rh8 and it worked to fetch some obspar files on RH8 and CentOS7.

I'd like to just add a unit test for the package in general but my preference would be to merge this PR and do that separately.
