Companion to the {@link SameDirSymbolStore}, handles the case where the imported binary
was located in a container file (eg. zip file).
<p>
Instances of this class are conditionally created by the 
{@link SameDirSymbolStore#createInstance(String, SymbolServerInstanceCreatorContext) registry factory method}
when it detects that the imported binary's {@link FSRL} isn't a simple local file.
