No need to clear the buffer of the Wire library.

[Koepel]

In the file "src/SparkFun_SHTC3.cpp" is in two places this code to clear the buffer before calling a Wire.requestFrom():

while (_wire->available())
{
  _wire->read();
}

It is not needed to clear the buffer. When the Wire.requesFrom() is called it clears the buffers and variables before starting the I2C session.
Explanation: Common-mistakes#4

This is not even a bug, but that code is not needed.

Thanks @Koepel - your document about common mistakes with Wire is also very interesting to refer to.

I've created a PR (#3) with what I think are the changes you suggest. I will leave the PR open until either someone else or I has the opportunity to test the changes and make a release.

Merged and released in v1.1.3.
