decoder/sidplay: Fix date field to have year but not company or author
Field 2 is called <released>, formerly used as <copyright>[1][2]. It is
formatted <year><space><company or author or group>, where <year> may be
<YYYY>, <YYY?>, <YY??> or <YYYY-YY>, for example "1987", "199?", "19??"
or "1985-87". The <company or author or group> may be for example Rob
Hubbard. A full field may be for example "1987 Rob Hubbard".
This change splits the <released> field at the first <space>, to retain
the <year> part.
The 51823 SID files in High Voltage SID Collection (HVSC) version 71
have the following distribution of dates:
