Implement Wire::end()

[FischerMartin]

Hey Guys awesome work with this project! Is it possible to upgrade/merge the wire.h library? I have some problems with an sensirion i2c sensor. With the new libary everything works fine, but sadly not with the old one.

the problem is in -> Wire\src\utility\twi.c

we have to upgrade these two files:

#include <avr/io.h>
#include <avr/interrupt.h>

@FischerMartin I do see that the current Wire lib shows 1.0 under library.properties. However, what do those two avr file have to do with the ESP?

Especially for this case, I need the wire.stop functionality, which is included in the 2.3.2 wire library.
This request is a bit older and I'm not 100% sure why I marked the scripts. Maybe I got some compiler issue while I'm trying the upgrade on my own way.

Wire is implemented with a custom library per controller. And, in fact, on base Arduino it's still 1.0 and has no ::stop member:

The functionality needed here is a Wire::end() method that shuts down the internals and leaves everything in a known state. In other words, the reverse of begin() + reset the object and any global state.
Help wanted.
