minor suggestion wrt to the humanreadable format for filename

[apiszcz]

GREAT mpv addin, thank you for the UI and update. For consistency and post processing I am using this

helpers.lu local ret = string.format("%02dh%02dm%02ds%03dms", parts.h, parts.m, parts.s, parts.ms) Always keeping hours, understand , 00h add little value for a human, but downstream it helps keeping the format the same.
