eModbus

What's Changed

• Allow attachServer(ANY_SERVER, ANY_SERVER, ANY_FUNCTION_CODE, client) to create an "open bridge". This will let pass any request to the client regardless of server ID, hence creating an unrestricted and unguarded access to the Modbus the client is controlling.
• Use tskNO_AFFINITY instead of NULL in xTaskCreatePinnedToCore by @guido4096 in https://github.com/eModbus/eModb...

What's Changed

• CI update by @bertmelis in https://github.com/eModbus/eModbus/pull/355
• Add function set timeout by @gary7530 in https://github.com/eModbus/eModbus/pull/373

This release is focusing on Ethernet fixes and additions, but is adding also functionality for servers and bridges:

• for ETH.h based Ethernet boards (like the WT32-ETH01) now a separate ModbusServerETH.h was created that is to be used instead of ModbusServerEthernet.h for these boards.
• The older special Ethernet library by @maxgerhardt was removed. eModbus now uses the [standard...

Serial handling

This release brings a major rework of the ModbusRTU handling. The arduino-esp32 core has integrated some more ESP-IDF modifications for UART handling from version 2.0.x on that we have adopted for eModbus.

Problem was, we fixedly required a HardwareSerial as the communication object for our RTU classes. This prevented other channels like ``Software...
