Description
Is your feature request related to a problem? Please describe.
I would like the detailed HTML coverage report to be a single file.
Initially i thought html-self-contained would do this, but it does not support the detailed output.
Describe the solution you'd like
A single HTML file containing the detailed report.
Describe alternatives you've considered
In theory i could transform/'merge' the current output after gcovr.
This would require parsing the HTML output and then 'merging' it, but seems the wrong way to do it.
Ideally i would like for gcovr to provide this functionality as it already has the data and just the output needs tweaking.
Additional context
I have made a proof-of-concept in https://github.com/smavridis/gcovr/tree/single_file_html.
As per the guidelines i opened this issue before creating a pull request for more feedback.
Let me know what you think, and thank you for gcovr.
