AS7343 tinkering

I’ve swapped the 550 and 555 labels around as well. Here’s the current code which shows the unscaled values when in wavelength label mode.
If gadgetoid wants to use it as the example code on github, then that’s OK with me. As a naive user I havn’t worked out how to do a Pull Request on github in order to upload my example.

# Edits by Tony Abbey 20240909 with button Y to toggle between channel and wavelength labels, and display
# the unscaled values above the bar graphs when in wavelength mode. Max values tweaked to give
# a more even set of bars with LED on a white paper reflection.
