Allow creating 64 MB piece size

[Pentaphon]

I realize that 32MB piece size support was added recently but it seems the new piece size support standard for most clients currently in use is 64MB.

• qBittorrent supports 64MB pieces and larger (and will create up to to 256MB piece sizes in Support creating .torrent with larger piece size qbittorrent/qBittorrent#19535)

• Transmission 4.0 supports up to 64MB pieces (as shown in Qt: Allow piece size selection on torrent creation transmission/transmission#3768)

• Deluge supports 64 MB piece size torrents

• BiglyBT supports 64 MB piece size torrents.

• https://github.com/kz26/dottorrent already supported creation of 64MB but that ability was lost in torf.

• py3createtorrent recently went to 64 MB in Is 16MiB a hard limit for max pieces size? rsnitsch/py3createtorrent#34

• uTorrent 3.x supports 64MB piece size torrents

• Tixati 3.x supports 64MB piece size torrents as of https://forum.tixati.com/support/7137

That's all the major clients in use today.

Please allow us to keep up with these clients by giving us the ability to create 64MB piece size torrents. That should be sufficient for years to come as torrents keep getting bigger and bigger.

Piece size is already unlimited. Just set Torrent.piece_size_max_default to 64 TiB or whatever you like. Just tested it with 128 MiB and it works. What exactly is your issue?

Sorry, I just wanted to make sure this was not getting in the way of torf-gui doing it, which I use. Closing this. Thanks.
