feat: Add automatic detection of output format from filename

[mtsfoni]

Description

This PR adds a feature to automatically detect the output format based on the provided output filename's extension. If the -fn (or --filename) option is set but --json or the future --bom-format option is not set, the format is derived from the file extension. Explicit parameters --json or --bom-format will take precedence if set.

Changes

• Added a new method SetOutputFormatFromFilename in Runner.cs to determine the format from the file extension.
• Supported extensions: .xml, .json, .proto, .pb, .bin.
• Integrated the format detection logic in the HandleCommandAsync method of Runner.cs.

Testing

• Tested with various combinations of filename extensions and format options to ensure correct format detection and precedence of explicit parameters.
