CLI documentation unclear

[letmaik]

The README says:

$ python cli/convert.py -i *name of input file(NetCDF)* -o *name of output file* -v *variable* -r *range type* [-t] *tiled* [-s] *tile shape as list*

The first thing is that this should say $ pycovjson-convert ....

When I run the tool without arguments, it outputs:

usage: pycovjson-convert [-h] -i INPUTFILE [-o OUTPUTFILE] [-t]
                         [-s SHAPE [SHAPE ...]] [-v VARIABLE]

Three things:

• Apparently there's no -r argument, I assume the README is outdated then.
• The -t argument doesn't accept values, so what does *tiled* mean in the README description?
• It's not clear to me how the -s argument should be used, an example would be good, especially considering the axis order.
• The -v argument is not specified as mandatory in the usage output. When I leave it out I get a very nasty exception.

Thought I had already updated this, will fix now

This can be resolved @letmaik @RileyWilliams

Markdown is messed up in the pycovjson-viewer section. Also, *tiled* is still in.

@letmaik can you check if this is resolved? I think it is.
