.. py:function:: str2array(s)

   Create a numpy int8 array using its compact representation saved as string.
   The input string might contain only digits and special characters.
   Every individual digit is treated as a new element, while the special
   characters induce special behaviour and include:

   - slash `/` - if present, divides main list into multiple sub-lists;
   - hyphen `-` - the next digit will be read as negative

   Please mind that the compact form used as this function's input is unfit
   to store floating point numbers or integers with absolute value above 9.

   :param s: input string containing only digits and special characters
   :return: a two-dimensional numpy array with integers
