Day 13: New design for jmp3, and fixed battery circuit errors

redid the design, ditching popout screen and replaced it with a round screen, like the ones used in smartwatches, then using only 1 rotary encoder for the controls. maybe ill add volume buttons separately for ease of use. but for now itll be just one rotary encoder.
fixed a few errors from my battery circuit
sketched in paint, itll look better than this lol
