Default to disassemble for CLI

[pirapira]

I tried to run the disassembler, and got the following error.

[16:20] yh@sri: ~/src/ethdasm$ python --version
Python 2.7.13
[16:20] yh@sri: ~/src/ethdasm$ cat test.hex 
0x60606040
[16:20] yh@sri: ~/src/ethdasm$ python ethdasm.py test.hex

Make sure you run it on Python 3.6+.

Thanks.

I'm seeing

$ python3.6 ethdasm.py test.hex
Traceback (most recent call last):
  File "ethdasm.py", line 40, in <module>
    print(output)
NameError: name 'output' is not defined
Error in sys.excepthook:

    import apt
  File "/usr/lib/python3/dist-packages/apt/__init__.py", line 23, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

Original exception was:
Traceback (most recent call last):
  File "ethdasm.py", line 40, in <module>
    print(output)
NameError: name 'output' is not defined

but I guess this is due to https://bugs.launchpad.net/ubuntu/+source/python3.6/+bug/1685596

Hmm, so it looks like you didn't pass in --decompile or --disassemble. There should probably be a default. I'll reopen this so I remember to add that.

python3.6 ethdasm.py --disassemble test.hex

Made the default command disassemble.
