Cannot disable colorizers on xlsx files.

[krackout]

It seems that colour support for xlsx files was added with this:
#1718

I recently updated from Visidata 2.11 to 3.0.2. I prefer to not have text and fill colours on xlsx files (as in v2.11), yet I cannot disable colorizers.
I've tried starting visidata --xlsx-meta-columns=False parametre, but unfortunately colours are still on. Also tried to switch theme to asciimono, yet xlsx files still load with colours.

If xlsx-meta-columns=False is supposed to disable colours on xlsx, I'm filling a bug report. Else sorry for misunderstanding and please guide me to the proper way of disabling them.

This would be useful, too. I like having the colors, however, there are spreadsheets where the color choice is not useful, and can make seeing the values in VisiData more difficult.
