Feature Request: Support "True Color" escape sequences in loki logs

24-bit "direct" RGB colors in logfiles

Sometimes logfiles use 24bit RGB color escape sequences to distinguish between e.g. different email addresses using a checksum or for other reasons. Supporting the entire RGB color space would be useful.

The escape sequences used by almost all terminals with 24-bit RGB support are:

ESC[ 38;2;⟨r⟩;⟨g⟩;⟨b⟩ m => Select RGB foreground color
ESC[ 48;2;⟨r⟩;⟨g⟩;⟨b⟩ m => Select RGB background color

Perhaps I should also open an issue on the ansicolors npm package? At a very quick glance, I wasn't certain if adding 24bit RGB color support there would be API compatible or would require an update to grafana.

@nevans we could use some help on this, could you verify if ansicolor supports this?

Sorry I lost track of this. No, it doesn't look like it does. I posted an issue here: xpl/ansicolor#17

Closing this as it's an issue in an external repo - and have posted to that repo.
