CalyxOS 3.x (Android 12) with Magisk with working signed images and AVB Verity

This idea was inspired by this post topjohnwu/Magisk#509 (comment)

I got this working with CalyxOS 3.3.1 (Android 12) with full AVB Verity enabled and was able to lock the bootloader after flashing and still have su. The OTA update zip generated was also tested against the Calyx 2.11.0 version (with Magisk) and it works well.

Create a working build

First, make sure you can build and sign a proper CalyxOS for your device. This is probably the hardest part.

Upgrade to at least 0.8.4

Using newer compiler versions and the optimizer gives gas optimizations and additional safety checks for free!

The advantages of versions 0.8.* over <0.8.0 are:

• Safemath by default from 0.8.0 (can be more gas efficient than some library based safemath).
• Low level inliner from 0.8.2, leads to cheaper runtime gas. Especially relevant when the contract has small functions. For

// Each mining pool that intends to provide flash loans deploys a Loaner contract and transfers ETH to it
// When testing each bundle, the diff in balance in this contract is taking into account for calculating effective gas price

# A Python script that decrypts the content of Kamstrup KEM file and imports meter files
# to wmbusmeters' config folder.
#
# The KEM file is a (sometimes zipped) xml file that contains xml-encrypted data using 
# the xml-enc standard (http://www.w3.org/2001/04/xmlenc). The password needed to decrypt 
# the xml-encrypted data can either be the CustomerId or something else selected by the 
# person that has created the KEM file using Kamstrup software.
#
# This script takes the encrypted KEM file and decrypts its content (it automaticly detects
# the zip archive and extracts the kem file from it). The result is a XML with a list of meters
