Inconsequential correction to IFM SBN246 temperature decode.

[swh76]

Description

I think the decode of the temperature data from the IFM SBN246 sensor drops the MSB here;

socs/socs/agents/ifm_sbn246_flowmeter/agent.py

Line 29 in 81e5916

_b_temp = binary[17:30]

From the IO-Link process data description;

but running a 32-bit word through the existing code;

value='abcdefghijklmnopqrstuvwxyz123456'
_b_flow = binary[0:16]
_b_temp = binary[17:30]
print(f'_b_flow = {_b_flow}')
print(f'_b_temp = {_b_temp}')

gives

_b_flow = abcdefghijklmnop
_b_temp = rstuvwxyz1234

which misses the MSB of the temperature process data field (letter 'q' here). This PR fixes that.

Motivation and Context

In my lab this makes no difference, probably because it would only matter if the temperatures were much higher. The same is almost certainly true in the field. This change probably doesn't matter, I just noticed it when I was working out the decode for a different IFM sensor.

How Has This Been Tested?

I compiled and tested on my two SBN246 sensors in my lab at SLAC and it made no difference.
