User should be able to specify a min and max value which raw sensor distances should be recorded

Some sensors have (short) intervals with measurement errors. This results in the sensor measuring a minimum of ~22cm and a maximum of ~6550cm. Allow the user to specify a lower and upper distance limit in cm. If the measurement is outside these limits, the data should not be stored.

• Added two adjacent form fields in the settings
• Check if measured distance is within this interval before saving data.
