parse_saa7134.pl: add logic to detect transactions without STOP

Read operations with sub-addresses are done by a write to the write address,
plus a read. Between the write and read, there's no stop.

For example, a read from eeprom, starting at eeprom address 0 will
be displayed as:

write_i2c_addr(0x50, 1, { 0x00}); /* INCOMPLETE */
read_i2c_addr(0x50, 23) /* 0xde, 0x17, 0x36, 0xb1, 0x54, 0x20, 0x1c, 0x00, 0x43, 0x43, 0xa9, 0x1c, 0x55, 0xd2, 0xb2, 0x92, 0xff, 0xff, 0xff, 0xff, 0xff, 0x20, 0xff */;
