Cargo manifest fixes

This fixes Cargo manifest, bringing option to statically link the library and removes 'lib' duplications from the crate name.

Performance optimisations

Eliminated needless extra iterations over tiles' groups and map prototypes.

Parse and export maps

This brings support for .map file format itself, as well as support for everything needed to accomplish this goal, such as .pro, .frm, .pal files' format support, example tools for testing the code and working with other resources, and more.

It has been tested with original Fallout™ release resources — every map in it's initial state has been exported correctly for every elevation it had. Every option and command available for mapview example tool has been also checked and confirmed to work properly.
