GetParams reads the shard's prefix to provide the correct parameters for the RS codec the packet requires based on the prefix on a shard (presumably to create the codec when a new packet/group of shards arrives).

GetShards returns a bundle of segments to be sent or stored in a 1kb segment size with redundancy shards added to each segment's shards that can reconstruct the original message by derivation via the available parity shards.

NewPacket creates a new structure to store a collection of incoming shards when the first of a new packet arrives.

Pieces computes the number of pieces based on a given chunk size.

SegmentBytes breaks a chunk of data into requested sized limit chunks.

Partials is a structure for storing a new inbound packet.

PartialSegment is a max 16kb long segment with arbitrary redundancy parameters when all of the data segments are successfully received hasAll indicates the segment may be ready to reassemble.
