feat: add Diversified Late Acceptance approach

[zepfred]

This PR adds a new acceptor approach: Diversified Late Acceptance approach (DLAS). The implementation is based on the work:

Diversified Late Acceptance Search by M. Namazi, C. Sanderson, M. A. H. Newton, M. M. A. Polash, and A. Sattar

[triceo]

Needs documentation.

In the docs, take inspiration from the late acceptance selector; remember to reference the paper, give a brief description of the difference between LA and this.

Also search for "preview" in the existing docs, and make sure to mark the feature as a preview the same way we do elsewhere.

The Spring failure will require a change to this, I think:

Last comments, then LGTM.

Not sure why Enterprise is failing. Intermittent failure?

It is also failing locally, and I'm investigating it.

@zepfred Sonar says there are unnecessary casts in the PR. Can you please double-check? (Sometimes it's a false positive, in which case I'll merge this right away.)

It is a false positive.
