feat: read retrobat's saturn and atari builds

RetroBat installs its stable archives, so each config_reads entry is
read at the build the binary names: Hatari 2.4.1, hatariB 0.3,
Hatari2014 at ab55c3e from the buildbot, Kronos 2.7.0 and Ymir 0.3.3.
SSF ships PreviewVer R28 and YabaSanshiro 1.20.32 has no public
source: binary_sha256 names the file their address refs are read in.
The seven RetroBat records citing an option list now hold.
