This PR adds a new module to the processor: a single-wire interface controller (ONEWIRE) that is compatible to the Dallas/Maxim 1-Wire protocol.

New top generic:

IO_ONEWIRE_EN : boolean := false; -- implement 1-wire interface (ONEWIRE)?

New top interface port:

-- 1-Wire Interface (available if IO_ONEWIRE_EN = true) --
onewire_io : inout std_logic; -- 1-wire bus

✔️ Tested with a Maxim DS18B20 1-Wire thermometer and a Maxim DS2413 1-Wire dual channel switch.

📢 See the discussion of this PR for more information: #403
