Added hex, c-hex and binary file output formats to the assembler.

I have added the ability to select output file format to the assembler, so it is easier to use the binary in other programs. Also I improved file i/o error display a little.

Now it prints usage:

usage: assembler.py <input_file> [output_file] [format]
available formats:
  lines-bin - ascii file contatining line-separated 16-bit binary numbers (default)
  hex - zero-padded 4-character hex
  c-hex - comma-separated c-style hex literals e.g. 0x1234, 0x456
  binary - binary file (big endian)

Formats:

lines-bin (default, original format)

1000111111111000
1111111100001110
...

hex

8ff8ff0eff0dff03ff05ff02ff018e14ff...

c-hex

0x8ff8, 0xff0e, 0xff0d, 0xff03, ...

binary

Outputs binary file (big-endian) containing the bytecode.
