[1.6.0] Minimum and maximum pool size limits

What's Changed

Added

• Added min_pool_size and max_pool_size configuration options to control the allowed range of base workers. add_idle_workers!/2 and remove_idle_workers!/2 respect these limits: extra workers that would exceed max_pool_size or drop below min_pool_size are skipped and an error is logged. See the documentation for details.
