Investigate chunk sizes

[geraintwhite]

The chunk sizes for a world generated in the multiplayer branch:

[('12.chunk', 16), ('4.chunk', 16), ('8.chunk', 16), ('18.chunk', 16), ('0.chunk', 64), ('7.chunk', 16), ('3.chunk', 16), ('5.chunk', 16), ('14.chunk', 16), ('17.chunk', 16), ('20.chunk', 16), ('6.chunk', 16), ('-1.chunk', 64), ('11.chunk', 16), ('1.chunk', 64), ('10.chunk', 16), ('9.chunk', 16), ('16.chunk', 16), ('-2.chunk', 64), ('19.chunk', 16), ('13.chunk', 16), ('15.chunk', 16), ('2.chunk', 16)]

A world from the master branch:

[('12.chunk', 16), ('4.chunk', 16), ('21.chunk', 16), ('8.chunk', 16), ('18.chunk', 16), ('0.chunk', 16), ('7.chunk', 16), ('3.chunk', 16), ('5.chunk', 16), ('14.chunk', 16), ('17.chunk', 16), ('20.chunk', 16), ('6.chunk', 16), ('-1.chunk', 16), ('11.chunk', 16), ('22.chunk', 3), ('1.chunk', 16), ('10.chunk', 16), ('9.chunk', 16), ('16.chunk', 16), ('-2.chunk', 11), ('19.chunk', 16), ('13.chunk', 16), ('15.chunk', 16), ('2.chunk', 16)]
