Bug fix release

• Due to sym-link usage in v0.11.0, Arduino Library Manager refused to index that version. The issue was fixed in this version by reorganization ESP-IDF component directory structure.
• No changes in the library sources against 0.11.0

• Breaking change: Parasite powering mode refactored.
  • Touch and write family of methods are augmented by an additional parameter power controlling the strong pull-up following the 1-wire operations.
  • OneWireNg::powerBus() should not to be used explicitly anymore to enable the strong pull-up.
  • DSTherm and OneWire classes updated accordingly.
  • The overall stability of the library in the parasitic mode has been improved.
• ESP-IDF and ESP8266 RTOS SDK frameworks support.
  • Supported ESP32: classic (Arduino, IDF), C3 (Arduino, IDF), S2 (Arduino, IDF), S3 (Arduino, IDF), H2 (IDF).
  • ESP8266 supported by Arduino and ESP8266 TOS SDK frameworks.
  • DallasTemperature example updated for ESP-IDF and ESP8266 RTOS SDK.
• Mbed OS based platform support (experimental).
• Time critical code improvements (mainly ESP32 and ESP8266).
  • CONFIG_BITBANG_DELAY_CCOUNT library configuration.
  • GPIO low level handling moved to IRAM.
  • The library is able to handle over-drive enabled devices for MCU frequencies < 40MHz.
• CONFIG_CPP_NEW_ALT configuration removed; CONFIG_USE_NATIVE_CPP_NEW added.
• Platform headers substantially refactored.

This is a bug fix release for v0.10.2.
Due to issues reported for ESP32 platform with CONFIG_BITBANG_TIMING configured as TIMING_RELAXED, the default configuration for this parameter is changed to TIMING_STRICT.

WARNING: Don't use this release. v0.10.3 is a bug-fixed version.

• CONFIG_BITBANG_TIMING library configuration. Note, the default value of this parameter is TIMING_RELAXED which differs from the previous library behavior corresponding to TIMING_STRICT configuration.
• CI/CD support added (GitHub Actions) + related unit tests fixes.
• Static code analyzer issues fixes.
• keywords.txt updated.

• Arduino Mbed OS based platforms support added (RP2040, Nano, Edge, Nicla, Portena)
• ESP32: deprecated CRITICAL_NESTED API replaced by INTERRUPT_MASK_FROM_ISR counterpart
• DSTherm driver: SUPPORTED_SLAVES_NUM constant added
• Configuration parameters may be set separately by -D compiler's option

• Breaking change: Search scanning loop refactored and simplified. See README.md and the examples how to update legacy code.
  • EC_DONE removed from OneWireNg::search() return codes. EC_MORE is an alias to EC_SUCCESS.
  • C++11 range loop: auto replaced by auto& for iterated slaves ids. OneWireNg::Id& is returned by an iterator instead of wrapper around this reference.
• MAX31850 and MAX31851 thermocouples driver.
• CONFIG_ESP8266_INIT_TIME library configuration.
• Overdrive mode fix (ESP8266) with some minor improvements.
