RS485 Hotline Protocol Receiver/Transmitter (#5)

* Hotline Protocol: DDigital I/O control over RS485
- Protocol: Docs and Implementation
- fire/: rs485 receiver using hotline for control of effect heads, pilots, etc.
- controller/: 13 input (with 1 broadcast) rs485 transmitter using Hotline
- added to ci

* fmt

* fix: controller input limit and last control ID

* refactor: naming

* fixes: from refactor & lint

* fmt

* remove debug

* feat: handle received messages for dio

* fix: track state changes

* fix: high state 0x01 not 0xFF

* docs: Input to Output Trace

* docs: fix readme for input controller

* megapoofer device id 0x01

* duplicate outputcontroller -> megapoofer & sign

* remove output_controller

* docs: fix pilot pin

* reduce inputs and handle device ID

* remove unused import

* MegaPoofer Device ID 0x01

* fix: ci and lint

* allow only MP or Sign to be run, or both

* refactor: Input Resilience & Combined Output Controllers
- Update Hotline Protocol to send 16 states in 2 bytes
- Combine Sign and MP output controllers with optional eval of dio states based on installation device_id
- Add Device_ID 0xFF for all outputs active.

* remove debug counter

* update ci for refactor

* lint and clippy fixes

* docs: update pin mapping to match new pilot convention

* add clippy and more docs

* remove chaos mode

* docs: correct DIO IDs

* docs: output controller

* docs: add effect head positions for sign

* docs: add relay and solenoid connections to trace table

* docs: add control switch connections

* docs: rearrange table and fix table headings

* Limit input to MegaPoofer or Sign only
- this allows for common wiring

* update pin out
- match inputs to outputs
- common pins for mp and sign
- remove arm button

* Remap megapoofer pins to maintain hotline id to state bit relationship

* Adjust delays and remove debug statements
