Skill Calculator Issues

[feored]

• Necromancer pet skills do not work, specifically desclines with id 34, 39 that seem to require getting information from MonStats.txt
• Sklvl(x.y) formatted desclines need to be parsed. Explanation here
• Sklvl values work but often seem off by one (e.g fire golem holy fire)
• Flooring needs to be added at the appropriate places in calcs.py
• Long term, the use of eval should be replaced with a proper parser e.g pegjs. The grammar is fairly simple once it has been preprocessed by the python files, mostly arithmetic expressions + the ternary operator.
