* added basic support for cmake (#127)
* renamed Winter Drop version from MC_1_21_3 to MC_1_21_WD
* updated world spawn location for 1.21.2 (cubiomes-viewer #340)
* tweaked mc version to text conversion (#128)
* removed properties field in structure config and added dimension field instead
* moved biome tree selection back to biomenoise.c as it's slightly faster and avoids globals
* added pale_garden biome with 1.21.3 (version TBA)
* added small end islands and better end surface generation (#117)
* added linked end gateway finder (#117)
* fixed inaccurate End generation at large distances from 0,0
* fixed incorrect biome in outer end rings
* fixed incorrect biome area size (#122)
* moved biomenoise from layers.h into its own object
* moved biome tree data into separate header files for each version
* added global for the biome tree data to make runtime providers possible
* fixed outpost not generating in cherry_grove
1) fixed biome exclusion filter no longer working for 1.17-
2) fixed ruined portal variations
3) separted quad base code with threading and filesystem dependencies into its own source file
Different versions, dimensions and variations are now bundled into a single Generator structure.
Areas (x,z,w,h) are largely replaced with a Range structure that supports 3D cuboids with scaling.
The scale now acts as a generalization that replaces layer access. Direct layer access will
have to be version specific, using the LayerStack.
(I.e. this update will unfortunately break much of the API.)
1) Update readme to include structure finders + removed outdated references to seed lists.
2) Removed example programs find_quadhuts.c and find_compactbiomes.c in favor of small examples inside readme.
3) Replaced search4QuadBases with a more general searchAll48. This does, however, redefine the format for quad bases.
1) Turned getStructurePos into a wrapper that deals with all structure types.
2) Major changes to accomodate for more sophisticated quad-base finders.
3) Classifying quad-bases according to certain properties which they fulfill.
4) Removed precompiled quad-base files, as they can be generated quickly now.
5) Removed tri-base finders (until there's a more accurate finder in future).
1) Layer functions now return an int and can terminate the generation.
2) This makes it possible to write much more accurate and faster biome finders.
3) The generator structure LayerStack is now stack allocatable and no longer requires a free.
4) Adjustments to make targets.
