Debugging quality of life imporvements: --preserve-crlf and --export-mapping [FILE]

LeStahL commented 7 months ago

I noticed recently that it would be very nice to have certain debugging information available, like

A --preserve-crlf flag to preserve line numbers (because I find myself using clang-format to find lines in the minified source manually a lot).
The mapping of ids, in a format like
```
main="a"
main.fragColor="a.b"
trace="c"
trace.dist="c.d"
main.@anonymous.i="a.@anonymous.e"
unneccessary=""
...
```
maybe exposed over a command line parameter --export-mapping file.txt? This would simplify identifying the origin of expressions that break in the minified source.

For the first point, wouldn't it be sufficient to use the existing --format indented flag?

Yes, that's exactly what I was looking for, thank you for pointing it out! (And sorry for not RTFM enough) :)
