D1 mini WLED shield

This PCB includes a level shifter for the LED data lines, a fuse for overcurrent protection. A ESP32 D1 mini running WLED, a DC barrel jack for unified power in, built in LM2596-5.0 circuitry to power the D1 mini from LED power supply, headers for a MAX9814 module for AudioReactive WLED, and a jumper to adjust mic gain control and 2 terminal blocks for LED hookup.

Board Fixes:

I fixed the mistakes I found:
fixed where I connected the level shifter to 12V,
put the fuse in the wrong spot,
used the wrong pin for GND on the DC jack for power in,
fixed the net of one of the pins of the diode.
I also moved the second LED output to the bottom of the board, due to space constraints.

changing dev boards and adding fuse

I made the choice to change from a esp32-c3 supermini to a d1 mini esp32 because of the classic esp32 recommended by WLED. I also added a fuse to protect against failures.
