v2.6.8 - HA 2023.9.1 required

[alexdelprete]

With HA 2023.9.x the new pymodbus 3.5.x introduced changes that caused a problem to the integration (Endian.Big in the code had to be changed to Endian.BIG):

Thanks to @marcolinux46 for insisting there was an issue (check #70 and #73). I had a hard time catching this one, but it seems to be fixed now.

In order to fix it though, I needed to force upgrade the minimum required HA version to 2023.9.1 in order to use the component. Sorry for the inconvenience.

I also updated the minimum scan interval (polling period) to 30s. Keep in mind that VSN300/VSN700 update data every 60s, from what I read in the docs.
