Feature request: Update ETA when "NORMAL MODE: Percent done..." is received via the serial console

[kazoob]

When starting a print from the printer's SD card, the plugin will never receive the M73 gcodes. However when those are executed by the printer, the following line is received on the serial console:

NORMAL MODE: Percent done: 82; print time remaining in mins: 220

A suggestion would be to update the ETA when these are received if M73 gcodes are not being received. This would enable the accurate ETA for SD card prints.

Thank you in advance!

It looks like create separate super-simpler plugin is easier than implementing complicated logic with getting ETA from different sources. Just created on in half an hour ( https://github.com/kanocz/octopi_eta_override ) but it's still untested - will do this in the evening once return home
(edit: just tested, it works :) )
