[FR] Plausibility Check before exporting, like: Different Values need different LCSC Numbers

[dartrax]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I find that I made a mistake that could have been detected by software. In this case, I forgot to change the LCSC Part Number for a copied part. So I have two parts having different Values but the same Part Number and no warning from software.

Describe the solution you'd like
If multiple rows with the same LCSC Part Number have different Values, a warning should occur upon exporting.

Describe alternatives you've considered
An alternative would be to match the Value column with the LCSC Params column. There could be a warning if (parts of) the Value wasn't found anywhere in the LCSC Params string.
