Fixing excessive memory consumption

[NWItaly]

I use an Arduino Uno R3 and I would like to use CalibrationHelper example, but it didn't compile for excessive memory consuption.

BasicReading

Before: Global variables use 573 bytes (27%) of dynamic memory, leaving 1475 bytes for local variables. Maximum is 2048 bytes.
After: Global variables use 275 bytes (13%) of dynamic memory, leaving 1773 bytes for local variables. Maximum is 2048 bytes.

ManualCalibration

Before: Global variables use 697 bytes (34%) of dynamic memory, leaving 1351 bytes for local variables. Maximum is 2048 bytes.
After: Global variables use 275 bytes (13%) of dynamic memory, leaving 1773 bytes for local variables. Maximum is 2048 bytes.

CalibrationHelper

Before: Global variables use 3023 bytes (147%) of dynamic memory, leaving -975 bytes for local variables. Maximum is 2048 bytes.
After: Global variables use 323 bytes (15%) of dynamic memory, leaving 1725 bytes for local variables. Maximum is 2048 bytes.

There's not Release_Candidate branch... Link

Thank you for this, I pay my respects to you!

No worries about the missing branch, we can just merge this into main.
