8ccdf8a3b5 Control Panel: Better steps and units in paramtree 
- Step r0 by 100 Ohms instead of 1 Ohm

dd30db95ba Control Panel: Use codenames for parameters 
Without cosmetic changes, avoid embedding display text in the code.

For displayed string representations, use the `title` key, or for
`ListParameter`s, use the dictionary mapping method instead.

dd9e5fe195 Control Panel: Nest readings into its own group 
This should be more intuitive to first-time users, as there is explicit

e3abe9384a PyThermostat GUI: No crushing paramtree spinboxes 
It might not be the case on some themes, but on the default Qt theme the
spinboxes are a bit too short for the containing numbers. See

3c80446fa1 ad7172: Correct postfilter rates and rejection 
The AD7172-2 Rev. A datasheet is inconsistent on the 50/60 Hz postfilter
rates and rejection figures between the *ENHANCED 50 Hz AND 60 Hz
REJECTION FILTERS* and the *FILTER CONFIGURATION REGISTER 0* sections.
Use the former section's figures instead.

The latter section is wrong since the 21.25 SPS figure is incorrect, as
the output data rate = 1 / (settling time), and 1 / (40 ms) = 25 Hz.
This seems to have been corrected in the datasheets for the rest of the
AD717x family, which have the same filter.

8a95eb9fb1 Update panic-halt to v1.0.0
