Position argument flexibility:
- get(), get_interpolated(), get_slope(), get_normal() now accept:
- Two separate args: hmap.get(5, 5)
- Tuple: hmap.get((5, 5))
- List: hmap.get([5, 5])
- Vector: hmap.get(mcrfpy.Vector(5, 5))
- Uses PyPositionHelper for standardized parsing
Subscript support:
- Add __getitem__ as shorthand for get(): hmap[5, 5] or hmap[(5, 5)]
Range validation:
- count_in_range() now raises ValueError when min > max
- count_in_range() accepts both tuple and list

Add methods to query HeightMap values and statistics:
- get(pos): Get height value at integer coordinates
- get_interpolated(pos): Get bilinearly interpolated height at float coords
- get_slope(pos): Get slope angle (0 to pi/2) at position
- get_normal(pos, water_level): Get surface normal vector
- min_max(): Get (min, max) tuple of all values
- count_in_range(range): Count cells with values in range
All methods include proper bounds checking and error messages.

Implement the foundational HeightMap class for procedural generation:
- HeightMap(size, fill=0.0) constructor with libtcod backend
- Immutable size property after construction
- Scalar operations returning self for method chaining:
- fill(value), clear()
- add_constant(value), scale(factor)
- clamp(min=0.0, max=1.0), normalize(min=0.0, max=1.0)
Includes procedural generation spec document and unit tests.
