`freenet-core`'s minimum version is 1.80 while `freenet-stdlib`'s version is 1.71. 1.71 was released three years ago. Bumping to 1.80 allows dropping `once_cell` in favor of using the standard lib. I disabled the default features for `chrono`, `futures`, and `semver` because they weren't used. Chrono is only used in one place and the type is constructed through FFI rather than calling its functions. Futures is used for its traits so the rest of it isn't needed. I removed `serde_bytes` in favor of `serde_with`. `serde_with` includes its own version of `Bytes` and `serde_bytes` was only used twice in the code.

chronochanges to save you some time.chrono::DateTime<Utc>is constructed in freenet-core/crates/core/src/wasm_runtime/native_api.rs. It's written directly to the contract's memory. The code for that, infreenet-stdlib, is here. This bypassesserdeand the native system entirely, so theserdeandstdfeatures aren't needed onchrono.
