Add ACA acquisition probability models

[taldcroft]

Description

This adds data files for the ACA acquisition probability model that gets used in chandra_aca.star_probs.

Testing

See sot/chandra_aca#140

This makes sense to me (as an independent PR that we can review and merge before the new model).

[matthewdahmer]

Do we need to increment the version for this and does this change require a Jira ticket?

[jeanconn]

I would figure we would just bother to increment the version on the "other" PR that will have the update to the model.

[matthewdahmer]

Including this PR in the upcoming release works for me as long as this PR can be merged in time with the ACA model update. If this PR affects a flight approved process upon promotion it should be accompanied by a Jira ticket though, and the ACA model is just about ready for promotion (all non FD approvals are in).

[jeanconn]

And with regard to "update to the model" I was speaking to the update to the acquisition probability model not the update to the aca thermal model. I leave it to Tom to say if he wants to get this in to the ACA thermal model update release.

[taldcroft]

Since these new files don't yet impact any flight-approved process I think we can just merge this without additional review. Does it make life simpler if we hold off on merging until version 3.46 is approved and deployed (FSDS-62)? There is really no urgency on this one apart from making review of other Ska PR's a little easier.

In that case there is no issue with merging this in at any time, thank you!
