Add collabs

[wlangera]

I added all collaborators, can someone approve?

Do you think some people (or all) should get author roles?

cre: the creator or maintainer, the person you should bother if you have problems. Despite being short for “creator”, this is the correct role to use for the current maintainer, even if they are not the initial creator of the package.

aut: authors, those who have made significant contributions to the package.

ctb: contributors, those who have made smaller contributions, like patches.

cph: copyright holder. This is used to list additional copyright holders who are not authors, typically companies, like an employer of one or more of the authors.

fnd: funder, the people or organizations that have provided financial support for the development of the package.

Thanks @peterdesmet. Indeed, some can become authors. I merge with the main to see if all checks work.
