wrong list indexing + IndexError while scanning

[zeinlol]

Traceback (most recent call last):
  File "Bughound/bughound.py", line 53, in <module>
    findings = p.get_functions(verbose)
  File "Bughound/core/parser.py", line 114, in get_functions
    code_snippet+= lines[line_number]
IndexError: list index out of range

When sources doesn't handle that list start index self elements from 0, but line_number is line index, that starts from 1, so when they try to get data from last liine, thy through IndexError

and of course, because of this issue all parsed output is wrong: data is taken with a shift
