sim800l is only capable of registering to the network right now.
It will be improved if the network connectivity on the mountain requires it

# Conflicts:
#	host/host_central_mast/src/main.cpp

defined pin numbers for managing data transmissions of I2C, SDI12, RS485.
initial setup for the client_central_mast client

- move several blocks of code to their own respective functions
- move some functions to Utilities and ApiData
- Remove several unused functions

Make the host send to the actual API of our server

See merge request !36

minor refactor, allow Resendmanager to handle throws if no SD card is available, logic to generate a protocol address

- move get_host_mac to RtcMemory implementation
- allow hardcoding of mac address of host on client

Refactoring changes, changes in ADC selection, Energy consumption sensor, added compilation tests

See merge request !35

minor refactors

moved TEROS10 to wolle Library, added tests that check if all libraries compile and run successfully on an ESP32 where no peripherals are connected (see TestSensorLibraries.cpp)

Rename ForteDR26 to DR26. Allow more fine grained adc channel selection, add constructor for easier use

15 Messages per transmission, better modem turn on / off

See merge request !34

Developed sensor test board.

See merge request !33

Mock client consisting of ESP32 board, 3V3->5V boost converter, ADS1115 module and two dendrometers.
Measurements made with PPK2.  Found issues:
-regular power consumption spikes of ESP32 while in sleep mode (every 250µs)
-smaller, irregular spikes of ESP32 while in sleep mode
-high continuous current consumption of ADS1115 while not required to measure (300µA). current consumption while not configured only 1.5µA
