Building library with SIMPLEFOC_DISABLE_DEBUG defined results in compiler errors

[swilliams-rdg]

I ran into a similar issue with the FOC library which appears to have been fixed in the dev branch of that repo

There are several places in the driver library where either Serial or SimpleFOCDebug objects are used without checking the macro or if Serial is defined

Most of the errors are in SimpleFOCDrivers/src/settings/SettingsStorage.cpp but there's one in SimpleFOCDrivers/src/encoders/tle5012b/STM32TLE5012B.cpp
