Reducing excessive I2C timeout

[maidnl]

This PR takes care of issue #492 .
There was a default timeout of 1000 ms in I2C communication.
Timeout has been reduced to 1ms.
However (although this is not a standard Wire function) a setTimeout() function has been added to Wire class so that users can tune the value.

@per1234 I renamed the function according to the request, however please note that in the current implementation of Wire (at least in Core-Renesas) the Wire class is derived from HardwareI2C class, that is derived from Stream. And Stream has already setTimeout function.
void setTimeout(unsigned long timeout); // sets maximum milliseconds to wait for stream data, default is 1 second
In my opinion it is better to use setTimeout name which is in line with the current class derivation scheme.

[per1234]

Stream has already setTimeout function.

That function has a different purpose from what is being implemented here.

Stream::setTimeout sets the timeout for the high level blocking functions of the Stream class (e.g., readBytes).

The function implemented here is setting a timeout for the low level communication. This is the reason why the function was intentionally given a distinct name in the AVR library, rather than shadowing the Stream class member, which would have made it impossible to set the Stream timeout.

Requested change has been made. Thanks!

As @HanzHager reported in #497 (comment), the parameter of the established setWireTimeout implementation is the timeout duration in microseconds:

https://docs.arduino.cc/language-reference/en/functions/communication/wire/setWireTimeout/#parameters

timeout in microseconds, if zero then timeout checking is disabled

However, in your proposal the argument is instead a timeout duration in milliseconds.

Please bring the function into compliance with the established standardized API for Wire library implementations.
