Currently flame graph generation requires a d3-flame-graph template to
be installed. Unfortunately this is hard to come by for things like
Debian [1].
If the template isn't installed then ask if it should be downloaded from
jsdelivr CDN. The downloaded HTML file is validated against an md5sum.
If the download fails, generate a minimal flame graph with the
javascript coming from links to jsdelivr CDN.
v3. Adds a warning message and quits before download in live mode.
v2. Change the warning to a prompt about downloading and add the
--allow-download command line flag. Add an md5sum check for the
downloaded HTML.
