[TriEmbed] FXOS8700CQ EOL, last orders December of this year

Tue Jan 26 16:56:06 CST 2021

The ISM303DACTR allows for vector magnitudes to be buffered instead of 
individual axis values but has none of the threshold and count features 
to only only interrupting when specific magnitudes are exceeded X times.
