Rough build - not working - Vivint DW11 Contact Sensor

[NorthernMan54]

This is my test build where I have been playing around with different things, this is not ready for release but hopefully will offer some inspiration around the events obfuscation algorithm.

I have been running this with the command line

make ; src/rtl_433 -f 344988000 -vvv -F log

And it outputs this

honeywell_decode: honeywell_decode - start
honeywell_decode: Bits 0-7a 1-01 2-6b 3-34 4-01 5-05 6-73 7-25 8-a7 9-6f

{"time" : "2023-12-04 18:55:22", "model" : "Honeywell-Security", "id" : 160357157, "channel" : 2, "event" : 52, "state" : "closed", "contact_open" : 0, "reed_open" : 1, "alarm" : 1, "tamper" : 0, "battery_ok" : 1, "heartbeat" : 1, "mic" : "CRC", "count" : 363}

The lines Counter LSB, CRC High, and CRC Low are my quick attempts at trying out various decode approaches.

The field id is valid and matches the sticker in the device, and count is also accurate. The event field is the undecoded event byte. The other fields are not accurate, and the CRC does not work
