fix: handle case where multiple results include multiple tables

[wojciechka]

Closes #61

Fixes the parsing by keeping an index of how many tables were already present when a new result was being parsed, which correctly detects when a new table was added.

I have not run unit tests as I am not really that familiar with Python tools and I did not find instructions on how to run them.

Hi @wojciechka,

Thanks for issue and PR. I added info about how to run tests into README.rst.

I prepared other PR: #64 because this approach doesn't handle following case:

#datatype,string,long,string,string,dateTime:RFC3339,dateTime:RFC3339,dateTime:RFC3339,double,string
#group,false,false,true,true,true,true,false,false,true
#default,t1,,,,,,,,
