Request to make the Oblists cumulative somehow

[ATHSE]

I have a number of assets that could be grouped using the *Oblist method in fadata.ini with different filenames. Currently FA2sp only supports a single filemask for a group/sub-category, and I request this be changed.

I don't have a preference for specific way to do this, if a new entry just directed back to the same Oblist used by something else, that would be enough for me.

If however you want to change the ini syntax, so the Oblist comes first and the filemasks are a comma-separated list instead, that's fine too.
