Build fails due to missing size_of function

[estelsmith]

Running a simple cargo build from the latest main (and libsql-server-v0.24.31) results in the following error:

error[E0425]: cannot find function `size_of` in this scope
   --> libsql-wal/src/shared_wal.rs:419:80

help: consider importing one of these items
    |
1   + use core::mem::size_of;
    |
1   + use std::mem::size_of;

Importing use std::mem::size_of; in shared_wal.rs seems to allow the build to complete. I'm not a rust dev and I don't really understand the difference between the two imports, so I figured I'd open an issue rather than a pull request.

EDIT: Running latest docker almalinux:9-minimal (eec681af155e) on linux/arm64
