Updated core library to 0.5.9, presenting these changes:

Changed
The routing algorithm has been updated with RTT-aware link costing, which should prefer lower latency links over higher latency links where possible
The calculated cost is an average of the link RTT, but newly established links are costed higher to begin with, such that unstable peerings can be avoided
Link costs are only used where multiple next-hops are available and will be ignored if there is only one loop-free path to the destination
This is protocol-compatible with existing v0.5.x nodes but will have the best results when peering with nodes that are also running the latest version
The getPeers endpoint will now report the calculated link cost for each given peer
Upgrade dependencies

Fixed
Multicast discovery should now work again when building Yggdrasil as an Android framework
Multicast discovery will now correctly ignore interfaces that are not marked as running
Ephemeral links, such as those added by multicast, will no longer try to reconnect in a fast loop, fixing a high CPU issue
The TUN interface will no longer stop working when hitting a segment read error from vectorised reads
The AllowedPublicKeys option will once again no longer apply to multicast peerings, as was originally intended
A potential panic when shutting down peering links has been fixed
A redundant system call for setting MTU on OpenBSD has been removed

Fixes in Android app
Fixed occasional crash on start/stop
Updated some dependencies
Updated Android API to 34
