When receiving seedlink dara for format of miniseed256, the slarchive throws an error: "sl_collect: non-miniSEED packet received!?! Terminating."

This is because the SeedLink specification only officially allows 512-byte miniSEED records. From https://www.seiscomp.de/doc/apps/seedlink.html:

When handshaking is completed, a stream of SeedLink “packets” consisting of a 8-byte SeedLink header (containing the sequence number) followed by a 512-byte miniSEED record, is sent to the client.

The next version of slarchive will support other miniSEED records lengths despite this limitation in the specification.
