Bump Straume version

[javra]

Could you bump the Straume dependency so that this compiles with the newest Lean version?

Hi, @javra, currently Lean libraries of Lurk-Lab aren't maintained as far as I know, and I don't have the time for maintaining them myself, since I'm actively searching for a contract right now :(

Some day I'll get back to maintenance, I promise, but it's unlikely to happen this year! :pray:

Do you accept PRs for small maintenance things?

@javra quite likely !
