Subject: [PATCH] Updated to zig 0.13.0 (#198)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Updated to latest zig

* feat(flake): update zig to 0.13.0 and add zls

This also disable diffs for flake.lock to not
not polute the git diff output too much

* feat(build): Update dependencies to support 0.13.0

* feat(build): disable broken examples

* feat(ci): Update zig to 0.13.0

* feat(rp2040): Update pio tokenizer tests to 0.13.0

* feat(build): Fix uses of deprecated std.zig.CrossTarget

* feat(rezg): Fix uses of deprecated std.mem.{tokenize,slice}

* feat(rp2040): Fix uses of depreacted std.rand

* feat(readme): Update zig version
