writeHex doesn't write to the output stream about midifile HOT 1 CLOSED

Finally fixed(!) with commit a48a2cb

I must have been thinking to use sprintf, but used printf by mistake... Obviously I have never used the save-to-file version of MidiFile::writeHex.

Here is a test program for creating a hex bytecode MIDI file:

test input file:

"MThd"
4'6
2'0
2'1
2'100

"MTRk"
4'13
v0   90 '60 '80
v200 90 '60 '80
v0   FF 2F 00

(a binary MIDI file also works as input).

output:

$ bin/midi2hex input.txt
4d 54 68 64 00 00 00 06 00 00 00 01 00 78 4d 54 72 6b 00 00 00 04 00 ff 2f
00

And using the -o option will save to a file without the accidental re-routing of the bytes to standard output:

$ bin/mid2hex -o output.hex input.txt

contents of output.hex:

4d 54 68 64 00 00 00 06 00 00 00 01 00 78 4d 54 72 6b 00 00 00 04 00 ff 2f
00

Such a great library! Thank you very much for sharing it, and the Options class is the best I've used.

Thanks! Yes, I cannot live without the Options class when writing command-line programs in C++.
