Check lot size <= coin decimals

I had a real fun error where the MarketProxy wasn't even making it to the Serum DEX. Turns out it was caused by a Mint decimal change during a refactor and the lot size became larger than the mint's decimals. So everything was failing silently. The market initialized fine, but posting orders failed to proxy because the instruction data got mangled.
A simple fix would be on initialize market & new order instruction creation, validate the lots against the mint decimals.
