ADS131M02 and ADS131M04 Arduino Library

Arduino lib for the ADS131M02 and ADS131M04 24-bit Analog to Digital Converter.

Mostly based on the work of https://github.com/LucasEtchezuri/Arduino-ADS131M04 and https://github.com/raibisch/ADS131M0x

My changes to Raibisch's lib

• Fix problem of channel offset when using ADS131M04
• Add example of using ESP32 cled as clock source for ADS131M0x
• Split ADS131M0x to ADS131M02 and ADS131M04
• Fix examples
• Add support for rp2040

Raibisch's change to original LucasEtchezuri's lib

• adaption for ADS131M02 and conditional code parts for ADS131M02 and ADS131M04
• modified interface for flexible SPI-Port
• method to change SPI clock
• minor changes for speed optimation
• additonal interface description

Please notice: all modifications are only testet with ESP32, rp2040
