IN:
      HL = 2, convert DEBC to stream IX
      HL > 255, pointer to 32 bits integer to convert

      DE = 0, write string to stream IX
      DE = 1, write string to filter IX
      DE > 255, string is written at (DE)

      A = formatting specifier
              A0 = 1, disable leading zero
              A1 = 1, output leading '$'
              A2 = 1, output trailing 'h'
              A3 = 1, lower case (a-f)

      IX = optional output handle (if DE = 0,1 or HL = 2)

OUT, if call successful:

OUT, if call failed:

Registers changed after return:
      A.BC..HL/IXIY same
