Enable output to both JSON and CLI

[zyrxvo]

Context:
The CLI output, especially with the --reduced-profile flag, provides concise, actionable, and human readable information for improving and optimizing code. Additionally, the JSON output provides verbose details, perfect to use for machine-automated interpretation and analysis of the results.

Changes:
This PR enables the ability to save both the CLI output and the JSON output from the same profile when both the --cli and --json flags are used in conjunction with --outfile.

Drawbacks:
In order to prevent overwriting the JSON file, the plain text file is forced to have a .txt suffix. For consistency the HTML files are all forced to have a .html suffix.

Comments:
I understand that the default behaviour is to produce a JSON file and an HTML file for viewing in the browser. The change in this PR reflects the desire to provide the option of having the human readable profile as a text file, rather than only with a browser.

Please address the CI issues above, thanks!

I addressed the CI issues by trying to keep the behaviour as similar to the original as possible. The only difference should be with --cli in combination with --outfile. Now, when --json is included, it also saves the table summary, either as it would be with only --cli or with --cli and --html.
