Review comment:
Big ? on that idea, i feel like it will save some code space since every
project rebuilds its own.
Glibc has a way to register custom printf handlers:
https://www.gnu.org/software/libc/manual/html_node/Customizing-Printf.html#Customizing-Printf.
I don't think we need to go that far, better a lightweight implementation that
just does a couple of common things - `ble_addr_t`, `ble_uuid_t`,
space-separated hex with a max width modifier - but the precedent is certainly
there.
