When the --reset_learning_rate option is specified,
it resets the learning rate stored in each layer of the network
loaded with --continue_from to the value specified by the --learning_rate option.
If checkpoint is available, it does nothing.

The fact that this method uses tiles is implementation detail. It does not change the result compared to Sauvola without tiles. The use of tiles minimize memory consumption.

Fix autoconf build for latest MacOS (Intel and M1)
...
On latest MacOS 11.3 the system header file "ostream" includes a file
named "version".
The macro DEFAULT_INCLUDES adds the source root to the list of include
directories by default. As MacOS uses a case insensitive file system,
the compiler finds and includes the file "VERSION" there which causes
compiler errors and a failing build process.
Setting an empty DEFAULT_INCLUDES fixes that, but requires moving
config_auto.h to another directory in the include search path.
