      Description

      When creating subtypes for binary objects > 127 then mongoexport exports in a format that mongoimport can't import.

      To reproduce:

      1) Save some objects in the shell

       
      > use pymongo_test 
      switched to db pymongo_test 
      > db.bin_test.find() 
      db.bin_test.save({'127': BinData(127,"aGVsbG8=")}) 
      db.bin_test.save({'128': BinData(128,"aGVsbG8=")}) 
      db.bin_test.save({'129': BinData(129,"aGVsbG8=")}) 

      2) mongoexport -d pymongo_test -c bin_test

       
      connected to: 127.0.0.1 
      { "_id" : { "$oid" : "50b871febfe8b9ae25f4e6d5" }, "127" : { "$binary" : "aGVsbG8=", "$type" : "7f" } } 
      { "_id" : { "$oid" : "50b87205bfe8b9ae25f4e6d6" }, "128" : { "$binary" : "aGVsbG8=", "$type" : "ffffff80" } } 
      { "_id" : { "$oid" : "50b87215bfe8b9ae25f4e6d7" }, "129" : { "$binary" : "aGVsbG8=", "$type" : "ffffff81" } } 

      3) Try to import:

       
      mongoexport -d pymongo_test -c bin_test | mongoimport -d pymongo_test -c bin_test2

      So only type 127 got exported and reimported.
