m_layer_name uninitialized in Writer.hpp

[ltog]

m_layer_name declared in https://github.com/ltog/osmi-addresses/blob/d87af1c6e2727d88ff5c5992b4c82fd9e36ba292/osmi/Writer.hpp#L50 is not initialized anywhere...

Usage of layer_name ( https://github.com/ltog/osmi-addresses/blob/d87af1c6e2727d88ff5c5992b4c82fd9e36ba292/osmi/Writer.hpp#L18 ) should be substituted with m_layer_name.

Strictly speaking, m_layer_name ist not uninitialized, but initialized with the default constructor, which initializes it to an empty string. Therefore no warning is generated, but the behaviour is nevertheless unexpected/undesired and should be fixed.
