`bsp.split_recursive` raises `TypeError` when `seed` is a `tcod.random.Random` instance

Describe the bug

bsp.split_recursive raises a TypeError when the seed parameter receives a tcod.random.Random instance, even though the type hint allows tcod.random.Random | None.

To Reproduce

import tcod

bsp = tcod.bsp.BSP(x=0, y=0, width=50, height=50)
random = tcod.random.Random()

bsp.split_recursive(
    depth=2,
    min_width=6,
    min_height=6,
    max_horizontal_ratio=1.5,
    max_vertical_ratio=1.5,
    seed=random,  # raises TypeError
)

TypeError: initializer for ctype 'union TCOD_Random *' must be a cdata pointer, not Random

However setting seed=random.random_c works fine. split_recursive could internally access .random_c for the type hint to hold.

Desktop (please complete the following information):

• OS: macOS 15.4.1
• Python version: 3.13.7
• tcod version: 19.5.0

Fixed in 19.6.0, released just now.

That was quick, thanks!
