v1.0.3 ESP32 support Added

ESP32 support added. Thanks to @wfang2002

v1.0.1 minor bug fixes.

1. Minor typo correction - setSampligRate -> setSamplingRate

2. Use correct field separator in keywords.txt

The Arduino IDE requires the use of a single true tab separator between the keyword name and identifier. When spaces are used rather than a true tab, the keyword is not highlighted.

Reference:

This is the first realease of the library

In this release, we have methods to read temperature and voltage. You can mix them as you want, one or another method, the library will read the correct value. The library also waits until the conversion finish, depending on the sample rate chosen. While wait for the conversion time interrupts are not blocked.
