uart_packet: decoder for logging and analysis of uart packets of variable length

[sespivak]

Decoder uart_packet stacks with uart decoder and allows to analyze data packets. Packet delimiter is idle time or maximum packet length. Output formats are same as in uart decoder: hex, dec, oct, bin and ascii.

'print_sec=yes' option can be used to log packets in real time:

sigrok-cli -d fx2lafw -c samplerate=1M --continuous \
           -P uart:rx=D4:tx=D5:baudrate=57600,uart_packet:print_sec=yes \
           -A uart_packet
uart_packet-1:    0.103 RX: AD 0C 80 00 80 80 80 80 80 00 00 00 00 00 00 A1
uart_packet-1:    0.301 TX: DA 03 00 00 B8 04 65
uart_packet-1:    0.303 RX: AD 04 80 00 00 00 00 29
uart_packet-1:    0.501 TX: DA 03 00 02 01 0C D6
uart_packet-1:    0.503 RX: AD 0C 80 00 80 80 80 80 80 00 00 00 00 00 00 A1

And one more example with input file:
