Replace TPL7407L with ULN2003A in Chainlink Driver BOM for now #181

Closed scottbez1 closed 2 years ago

The chip shortage doesn't seem to be letting up, so probably best to replace the TPL7407L with a ULN2003A, which is pin-compatible though slightly less efficient. Probably JLC/LCSC part number C7512, which also has the advantage for low quantity orders that it's a basic part instead of an extended part, so it saves a $3 flat fee.
