    Summary: Work out if we have space for one tonne of cargo
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * Main flight loop (Part 8 of 16) calls tnpr1


 Given a market item, work out whether there is room in the cargo hold for one
 tonne of this item.

 For standard tonne canisters, the limit is given by the type of cargo hold we
 have, with a standard cargo hold having a capacity of 20t and an extended
 cargo bay being 35t.

 For items measured in kg (gold, platinum), g (gem-stones) and alien items,
 the individual limit on each of these is 200 units.


 Arguments:

   A                    The type of market item (see QQ23 for a list of market
                        item numbers)


 Returns:

   A                    A = 1

   C flag               Returns the result:

                          * Set if there is no room for this item

                          * Clear if there is room for this item
