Goals

demystify the LPC55 ROM bootloader (at least for people who know Rust), by
- modeling "protected flash" settings and other sparsely documented data as Rust types
- implementing its protocol, removing leftover details for older chips
- clarifying the cryptographic details
unify
- NXP's elftosb, blhost and spsdk projects
- molejar's pyMBoot
- ergonomic corresponding TOML-based config files
library-first (independent of CLI), and an HTTP interface
support for non-file based signing keys (via PKCS #11 URIs)
