Description:
  The program has two parts:

  - To print the bow, a loop with a table is used, this is only two bytes
    shorter than printing the 3 characters directly.

  - To print the gift, a loop of rows and columns is made keeping a counter to
    change the symbol each 9 characters. This counter is done using a rotating
    bit through carry.

  To assemble the source, use the MADS assembler.
