New arduino library to use piezo buzzers in a non-blocking and easy way

I published a new library for Arduino on the registry. I know this type of library already exists but this one may be interesting for the purpose of creating small melodies and prompts when a user is navigating a UI in an embedded product (for example, clicks on start and you hear ti-ting). This one is not for long melodies like gmarty2000/buzzer for example, which lets you play any sound back-to-back.

@maxgerhardt A few weeks ago you made a PR on my other library (jcsb1994/tact) and I applied the changes to this lib too. hopefully it is Okay. PS after accepting your PR, I need to publish a new version of tact right?
