yeah, i now reduced it to `u16`, now it's down to 24kb and fits.

but maybe there's anyway a better way to do this?

i need to sample an ADC value at 6kHz and want to do this over 2s to get a stable measurement. then i want to return the mean, standard deviation and min/max.
i could of course calculate the sum while i'm on it, but for the standard deviation i need the values, so i can't discard them.

initially i had the code on the host side, but then i realised that requesting samples at 6kHz via `postcard-rpc` is not gonna work (let's just say i didn't think that one through... 😅), so i now moved it to the device.
