Support for remaining time in total minutes

[luke321]

Hello,

thank you for this great tool, I want to use it to create M73 commands for my Prusa Printers out of simplify.
Unfortunately the M73 command expects the remaining time to be in minutes, gcodestat only has the option in custom M117 formats to use remaining time in seconds %S.

Could you add the option to also have minutes eg.: minutes + hours *60 + day * 24 * 60 ?

Thank you!
