Detailed Description

All methods and objects related to the FastaBuff object.

The FastaBuff object is a memory efficient buffer for FASTA data. It stores the data in a packed format, with each byte containing two 4 bit values. This allows for a 50% reduction in memory usage compared to a regular byte array. The object also provides methods for easy manipulation of the data.
