Provides bounded and unbounded pools for any type of resource, as well as pools specific to Vec<u8> buffers.

The resource pools can have a user-chosen init_resource function run to create a new resource, and whenever a resource is returned to the pool, a reset_resource callback is first run.

The buffer pools use these features to create new empty Vec<u8> buffers as resources, and whenever a buffer is returned to the pool, the buffer is either cleared (without changing its capacity) if its capacity is at most a user-chosen max_buffer_capacity, and is otherwise replaced with a new empty Vec<u8>.

The unbounded pools all have a trim_unused function that can discard an excessive number of unused resources or buffers. Together with the max_buffer_capacity setting of the buffer pools, the amount of unused memory in a pool can be limited.
