Preview to check what I am working on is right

Thanks @f-ludlam this looks fantastic 🎉 ! All of the information looks good and the extra metadata looks useful too. As we discussed offline since we're adding new fields to the metadata we'll also have to update the types too at some point (the CI should fail because of this, so don't worry about any red crosses on this PR).

It might be best to carry on importing the rest of the data, adding new fields as you come across new metadata that needs to be encoded and then at the end we can do one pass over the types to update them with the new fields, or we can do it incrementally adding say 2015-17 + types now ?

To provide some extra information about what I mean by types, currently the metadata for the workshops is described by OCaml types here: https://github.com/ocaml/ood/blob/main/src/ood/workshop.ml and you can see for example we have a type for the presentation that looks like:

type presentation = {
    title : string;
    authors : string list;
    link : string option;
    video : string option;
    slides : string option;
    additional_links : string list option;
  }

Hopefully the correspondence with the yaml is self-evident. You've added a new field called type to describe if the presentation was a Poster or not, which is great, but we'll need to update all of the workshop types to match it so we generate and parse the data correctly at some point :)) Let me know if you want to carry on importing or if want some help with the OCaml side of things.

Just need a make fmt and we should be set, thanks @f-ludlam :))

Fantastic! The CI is actually now broken because it is incompatible with opam 2.1.0. There's a fix upstream, but I checked this out locally and tested and looks good to me. Merging now :)

Excellent work, @f-ludlam!
