Updated libraries (button and audio player) (#16)

This PR updates two dependency libraries to their latest versions:

## espressif/button: v3.5.0 to v4.1.5

[Version 4](https://components.espressif.com/components/espressif/button/versions/4.1.5/changelog?language=en) changed the API.  This code makes use of the new API, with no change to the existing behavior.

## chmorgan/esp-audio-player: v1.0.7 to v1.1.0

[Version 1.1.0](https://github.com/chmorgan/esp-audio-player/releases/tag/v1.1.0) introduces the possibility of multiple simultaneous audio streams.  This feature is as yet unused by KTag.
