0.31.0

Features and enhancements

• [core] Do not store node id for error raisers and save 2 bytes of RAM for each error raiser node. (#1841)
• [core] Optimize transaction state keeping. Single bit flags now share common bytes which leads to overall RAM usage decrease. (#1850)
• [core] Make port type castable to string type (#1857)
• [core] Wrap tabtests code into sections. When they fail it is easier to find the line causing the error. (#1860)
• [core] Change error clear conditions. Pulses no longer lose error state at the end of the transaction but stay in error until node re-evaluation. (#1858)
• [nodes] BREAKING ❗ Replace UPD inputs pins on idempotent actuator nodes with the ACT input pin: xod-dev/pn532-nfc/nfc-scanner, xod-dev/servo/servo, xod/common-hardware/h-bridge-dc-motor, xod/common-hardware/led. (#1842)
• [ide] Highlight a few more core functions in C++ editor (#1859)
