Will V2 support I2C clock stretching? about pi4j-v2 HOT 5 CLOSED

I had this issue myself when writing to an eeprom, and my solution was to set a new clkt_tout which was set in /etc/rc.local after startup. I found a howto here: https://github.com/raspihats/raspihats/blob/master/clk_stretch/i2c1_get_clkt_tout.c

Binaries are compiled and available here: https://github.com/eitch/raspi-builder/tree/develop/bin-files64

But yes we can try the overlay and see if that solves the issue too.

@FDelporte With the linuxfs-i2c plugin, I2C clock stretching will remain an issue that needs to be solved by setting register in memory. This will require root access, but is something that could be set at OS startup, and does not need to be solved by pi4j.

@eitch is this something that can (easily) be documented or described on the site on
https://pi4j.com/documentation/io-examples/i2c/ ?

@FDelporte Pi4J/pi4j.github.io@18fa2cd this fine?
