OTP Directory APIs

Bump… follow along on whitelabel OTP thread…

OTP whitelabel options for RP2350 boards

Current state of affairs is now reflected by following PR (which is both to/from my own fork, and should never be merged … it’s only for those curious…) Found a nasty bug that’d corrupt the OTP. Still lots more testing to do. The OTPDIR functionality has a framework which will likely work well, but it’s entirely untested code. On the plus side, it has a ton of RTT debug output. Externally-facing API is next up (and summarized in the above PR).
