Rust implementation of GA4GH Refget sequence collection functions

This module provides functions managing and retrieving sequences from a sequence collection.

Functions

The module includes the following main components:

• alphabet.rs - Defines various sequence alphabets (e.g., DNA, protein, ASCII).
• collection.rs - Contains the SequenceCollection struct and methods for managing sequence collections.
• digest.rs - Implements functions for calculating and verifying sha512t24u and other digests.
• encoder.rs - Contains functions for encoding sequences into compact representations.
• fasta.rs - Provides functions for reading and writing FASTA files.
• store.rs - Implements a sequence store that allows for efficient storage and retrieval of sequences indexed by sha512t24u digest.
