Add new symbols for DS2431+
Add new symbols for DS2431+.
This adds three new symbols for the same chip in three different form factors: for TO-92, TSOC and TDFN. The other form factors might not be relevant for soldering.
| TO-92 | TSOC | TDFN |

I likely need to fix more stuff anyway, like descriptions. I don't know whether drawing multiple non-connected pins on top of each other is acceptable (according to comments below it should be).
Datasheet:

- https://www.analog.com/media/en/technical-documentation/data-sheets/DS28E07.pdf (a different one, for almost the same chip; I'm using that one right now)
Maybe we need some generic model for 1-wire EEPROM first (similar to Relay_DPDT which is just a generic symbol for "any DPDT" relay that could be used for specialized components), and let all other chips derive from that. Because many more components require the same symbol, Analog alone lists 22 different parts under this category:
But I don't know whether there are many different manufacturers with different packages and pin assignments to make such a generic component problematic.

Notes about configurations that are not meant for soldering:
-
Remove the instructional content of this template -
Provide a URL to a datasheet for the symbol(s) you are contributing -
An example screenshot image is very helpful -
Ensure that the associated footprints match the official footprint library -
If there are matching footprint PRs, provide link(s) as appropriate -
Check the output of the automated check scripts - fix any errors as required -
Give a reason behind any intentional library convention rule violation.
