UPdate base to use kern-6 and update pybdsf

[Athanaseus]

resolves #675

[ratt-priv-ci]

Can one of the admins verify this patch?

I'll slap a DON'T MERGE label on it just for the moment, because switching everything over to KERN-6 seems like at least a minor (second-digit) release so maybe a bit more choreography is needed.

Should we do a 1.6.8 release with #678 #680 #682 merged, then release Caracal 1.0.4, then do Stimela 1.7.0 with this PR?

Please, let's do that, that way we can include @Mulan-94 's PR in Caracal 1.0.4 too.

Which @Mulan-94 PR is this?

caracal-pipeline/caracal#1249. Relies on #680 .

Ah yes, hence my concern here: #680 (comment)

Yes, from what I see, @Mulan-94 has removed gaintype from ragavi invocations in CARACal, but it's a chicken-and-egg problem, as in we need new stimela to confirm CARACal runs fine with #680 ( and because I am too lazy to change stimela back-and-forth while testing multiple CARACal PRs).

Yers, which is why I made suggestions on #680 which should get around this, hopefully straight to the mammalian stage.
