BUGFIX: Fixes issue where data offsets were not set correctly when exporting large FCS files (issue #12). Thanks to @andreas-wilm for PR #13.
BUGFIX: Export of FCS files would fail in rare cases where the text section byte length would be off due to the length increasing by one digit (leading to incorrect DATA section offset).
API: FlowData attribute cur_offset is no longer public (is only used internally in the constructor)
