Fix Srecord file parsing

[benedekkupper]

Closes #18

[Copilot]

Pull request overview

This PR addresses S-record parsing failures when termination (S7/S8/S9) records are missing by ensuring pending data is flushed at EOF, and strengthens detection of overlapping segments.

Changes:

• Flush pending SREC segment data at end-of-file even without S7/S8/S9 terminators.
• Throw an explicit exception when parsed segments overlap instead of silently ignoring the add.
• Bump package/project versions and add comprehensive file-format parsing tests (Intel HEX + SREC).
