1.0 (2018-11-02)

Backwards incompatible changes

The icemac.songbeamer.SNG instances no longer store the data on the data attribute but it now behaves like a dict thus allowing direct dict access to the data.
It is no longer possible to use attributes on icemac.songbeamer.SNG instances to read and store encoded bytes data. Either read/write text data from/to the icemac.songbeamer.SNG instance using the dict API or use the parse function (see next item) to import resp. use .SNG.export() to export the data encoded.
Add a function icemac.songbeamer.parse() converting a byte stream into a icemac.songbeamer.SNG instance. It replaces the class method on the SNG instance. It returns None if the data cannot be parsed and it logs an error message.
Drop support for Python 3.5, 3.6 and PyPy3, thus only supporting Python 3.7 now.

Features

Add a function icemac.songbeamer.open() to open a file given by a path and get a icemac.songbeamer.SNG instance.
Make .SNG.export() robust against missing text in songs.
Add a command line script songbeamer-xls-export exporting titles and song book numbers from folder containing SongBeamer files to an XLS file. To be able to use it icemac.songbeamer has to be installed with the xls extra like this:
```
$ pip install "icemac.songbeamer[xls]"
```
Support UTF-8 encoded SongBeamer files starting with the UTF-8 BOM.
Change license from ZPL to MIT.
