Cairo v2.4.0 introduced the notion of editions. New editions add new features but may include breaking changes. Editions are linearly increasing, i.e. if we have edition x<y<z, then we cannot upgrade to z without taking y's changes as well.
This PR adds edition to the project's Scarb.toml and makes the necessary changes so that the package compiles successfully. Edition 2023_10 narrows the part of the corelib which is available by default. To compile with this edition, this PR adds a bunch of use statements (mostly for

) for functionality that is no longer part of the prelude.PR Checklist
