FileSpan class abstract

A SourceSpan within a SourceFile.

Unlike the base SourceSpan, FileSpan lazily computes its line and column values based on its offset and the contents of file. SourceSpan.message is also able to provide more context then SourceSpan.message, and SourceSpan.union will return a FileSpan if possible.

A FileSpan can be created using SourceFile.span.
