Adjust LM75B/C layout (compact and swap I2C side)

John Beard requested to merge johnbeard/kicad-symbols:adjust_lm75b_layout into master

This is one that's always irked me!

This is a re-layout of the LM75C (and the derived LM75B) I2C temp sensor.

Two changes:

  • Make it a lot more compact (especially as this is a part that often nestles near something compllicated!)
  • Put the I2C on the right and the address straps on the left. This isn't really a fixed convention as such, but at least the address pins are more often than not on the left, and the I2C is a "notional" output from this device, even if not electrically.

This also makes it pin-for-pin compatible with the TI TMP1075D and NXP PCT2075DP, though they have slightly different manufacturer pin names:

I can add the thermometer to the others if desired in this MR.
