Store a dump of the data in a binary file.
Notes
The function creates a folder __lingpy__ on your system containing a binary file called FILENAME.bin with FILENAME corresponding to the name of the original CSV-file. Instantiating the same Wordlist instance again will first check for already compiled binary files and, if they are there, load them instead of the CSV-file.
