* Macro to load LP core code * Fix imports, add CHANGELOG.md entry * Avoid code warning * Omit path from function signature * More error checking * Clippy fix * Include the ELF used by the lp_core_basic example * Make object dependency optional * Use 1.65 for RISCV MSRV check * Use RUSTC_BOOTSTRAP for RISCV MSRV check * Remove the pre-compiled LP core example * Pin toml_edit in esp32c6-lp-hal-procmacro
