Default Use Fix

[Teque5]

• Current implementation doesn't produce any output in the svg with no arguments. Specifically you have to add -b to produce valid output. Maybe remove this switch.
• set marker generator as executable
• first line should be #!/usr/bin/env python3 to run on any system
• Dictionaries up to 5X5 work for me. 6X6 and 7X7 get this error:

Total marker size is going to be 600mm
Ground Sampling Distance is a maximum of 10.4mm/pixels, fly accordingly
Your marker has been created and is available here ./6X6_100_0.svg .
Traceback (most recent call last):
  File "./marker_generator.py", line 699, in <module>
    generate_marker(marker_id)
  File "./marker_generator.py", line 382, in generate_marker
    svg.add(createPixels(svg, bits, datawidth, border, margin, white_color))
  File "./marker_generator.py", line 287, in createPixels
    if not border or bits[i * datawidth + j]:
IndexError: list index out of range

• Dictionary arg should call 'upper' so that using "5x5_100" and "5X5_100" both work.

Hey,

I didn't see your comment before. Thanks for your input, I'll keep this open and integrate a fix for your suggestions.

I suspect there is an issue with the availability of the 7x7 and 6x6 dictionaries, I'll dig into this.
