Commercial vendor/interlink for chem

[Lopz]

Aside from the interlink used to send free supplies to medbay, chemistry could have a seperate one that sends chems to a vendor in front of science to sell them for a custom price, similarly to the gene booth. I think this would both encourage scienctists to make fun chems the crew would be interested in, and give them a convenient way of presenting said chems to the crew (while also making some money)
