Add support for Shenzhen EGQ Q85 and improve Abarth 124 Spider TPMS

[ProfBoc75]

Hi,

This is a PR related to #2556 Analyzing Shenzhen EGQ TPMS , similar to Abarth 124 Spider but not properly decoded. Issue reported by @js-3972.

3 majors gaps have been identified and added into this PR:

• EGQ Q85 data layout is common to Abarth 124 Spider (72 bits) plus a CRC 16 CCITT-FALSE data (96 bits).
• Temperature (°C) offset is 55 C instead 50
• Pressure (KPa) is by 3 instead of 1.38

This PR is in a conflicting state and needs to be rebased/cleaned up.
