Function touch_bond 

pub fn touch_bond(
    bonds: &mut Vec<StoredBond, umsh_journal_store::::ble::touch_bond::{constant#0}>,
    address_kind: u8,
    address: [u8; 6],
) -> bool

Move the bond matching address_kind + address to the MRU end, if present and not already there. Returns true when the order changed (and the caller should persist), false when the bond was already MRU or is not stored at all.
