Add support for Inno Setup 6.4.2 through 6.5.4

Added version strings for Inno Setup 6.4.2, 6.4.3, and 6.5.0-6.5.4.

New fields in header structure:
- close_applications_filter_excludes (added in 6.4.2)
- seven_zip_library_name (added in 6.5.0)
- NumISSigKeyEntries count field (added in 6.5.0) - read to maintain stream position
