13.0 stable

New specifications:

• PJON v4.0 includes the hardware identification, the hop count and deprecates the asynchronous acknowledgement
• PJDL v5.0 includes a coherent specification of timing and tolerance of each mode, a new preamble able to reduce retransmissions and specifies the timeout to be derived from the length of the frame instead of requiring a common static configuration
• TSDL v3.0 includes a more reliable acknowledgement exchange

Changelog:

• Sender's and recipient's MAC address can be optionally included and used for addressing
• The hop count is included in shared mode to enable more advanced routing schemes
• The library can now be included and used more easily, see configuration
• SoftwareBitBang implements PJDL v5.0
• SoftwareBitBang full support for STM32F103/BluePill added by @jcallano
• ThroughSerial implements TSDL v3.0 and receives data asynchronously
• Zephyr support and examples by @Cimex97
• Routing improvements and examples by @fredilarsen
• The LINUX interface now uses termios2 for generic baudrate support by @callalilychen
• The LINUX interface delayMicroseconds now uses select to reduce the CPU usage by @Girgitt
• ESPNOW can use MAC addresses directly by @porkyneal
• Send functions can now receive a PJON_Packet_Info, see documentation
• The asynchronous acknowledgement has been removed
• Bus id getter and setter added

Bugfix:

• Fixed ThroughSerial and ThroughLoRa acknowledgement vulnerability in multi-master mode
