Oscilloscope: Automated Measurements widget does not scale

[marcnause]

Describe the bug
The Automated Measurements widget in the oscilloscope screen does not scale automatically. It looks good on my phone, but it is very small in the desktop version.

Expected Behavior
The widget scales so that it uses the available space and can be read without a magnifying glass.

Steps to reproduce it

1. Open the desktop version of the app
2. Open the oscilloscope screen
3. Click the 3-dot menu icon in the upper right
4. Select "Automated Measurements"
5. Activate "PSLab Mic"

@marcnause I have made following changes, If it looks good i can create a PR:

Width of widget:

width: (constraints.maxWidth * 0.18).clamp(100.0, 200.0),

Font size:

double responsiveFont(BuildContext context, double baseFont) {
  final width = MediaQuery.of(context).size.width;
  final scaled = (width / 1440) * baseFont;
  return scaled.clamp(8.0, 32.0);
}

result:

I think the size must be changed depending on the height of waveform widget. If I remember correctly, there can be up to 4 Automated Measurements widgets which are stacked on top of each other if all 4 channels (CH1, CH2, CH3, Mic; requires connected PSLab board) are active. In your screenshot it looks like there is not enough space for 4 Automated Measurements widgets.

I've created a grid to reduce height, also font size is clamped so height of these widgets will not overflow
