[LT 2.0] Add AnnounceEndpoint:swig and peer_info::get_pieces methods

[proninyaroslav]

I'm currently migrating my app to jlibtorrent and have encountered a couple of methods that are missing from jlibtorrent:

• AnnounceEndpoint:swig
• peer_info::get_pieces

I'm using announce_endpoint to get getLast_error and get_pieces is used to calculate torrent availability and relevance value.
I'll try to figure out swig and maybe I'll be able to add these methods and make a PR.

why... :(

I know I know...lacks of update. Is there something I can do for you keep using libtorrent4j?

@aldenml
Hi. I didn't mean to upset you. I'm very grateful for your work, and I would like you to continue releasing updates, but without updates I don't see any other options. For example,

1. The problem with bdecode_node hasn't been solved.
2. Also, since the beginning of 2023, users have started to face mass bans of incoming peers Mass ban of all incoming peers arvidn/libtorrent#7734. I don't know what the reason is, maybe it's fixed in upstream, but without updates from upstream I don't even have a chance to check it.
3. I would like to have a working posix_wrapper again for SAF, or the ability to write a custom disk_interface to interact with SAF Add an ability to set custom disk_interface aldenml/libtorrent4j#269

@proninyaroslav I understand and I'm also grateful for you picking libtorrent4j early on. The 2) could be difficult to figure out, and yes, maybe that's a problem only in master upstream. Hopefully, I can release an update before you complete the migration :)

On version 1.2 I don't have any problems. Maybe the problem is not bugs, but updates.

please send 2 separate PRs, each on a separate feature branch so I can easily test.

Also notice we are now on the libtorrent 2, if this is for 1.2 make sure to create the branch off of the 1.2 branch (which we more likely not be maintaining, volunteers for that branch welcome)
