terminate called after throwing an instance of 'ZlibDecompressor::DecompressError'

Might be due to kinda corrupted map, Minetest just crashed with

I have just tested this version https://github.com/Rogier-5/minetest-mapper-cpp which works without complaining.

Closing because #5 describes this issue more nicely.
